David S. Miller 3a5fc21815 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2014-08-27

This series contains updates to i40e and i40evf.

Carolyn provides two patches, first changes the wording of the flow
director add/remove and asynchronous failure messages to include the
fd_id to try and add some way to track the operations on a given fd_id.
Second adds a check during handle_link_event for unqualified modules
when link is down and there is a module plugged in.

Anjali provides four patches to i40e/i40evf.  First update flow director
messages so that a user can tell if a filter was added or deleted.  Then
updates the ATR policy to not auto-disable ATR when we have errors in
programming.  The disabling of ATR when we got programming errors was
buggy and was still adding new rules and causing continuous errors.
With this policy change, we flush instead when we see too many errors.
In addition she adds a flow director flush counter to ethtool to help
know how many times the interface had to flush and replay the flow
director filter table.  Updates the driver to ignores a driver
perceived transmit hang if the number of descriptors pending is less
than 4, and instead log a stat when this situation happens.  This is
because the queue progresses forward and the stack never experiences
a real hang in these situations.

Shannon provides three patches for i40e/i40evf, first enables the
l2tsel bit on receive queue contexts that are assigned to VFs so that
the VF can get the stripped VLAN tag.  Then adds a max buffer size
parameter to the print helper to be sure the code knows when to stop.
Lastly, remove the complaint when removing the default MAC VLAN filter.
This was because old firmware had an incorrect MAC VLAN filter that
needed to be replaced at startup, and now newer firmware does not have
this problem.  So now we only add the new filter if the removal
succeeded and no need to complain if the removal fails.

Ashish provides a change to vsi->num_queue_pairs to equal the number
that is configured by the VF.  This limits the number of queues that
are enabled/disabled and fixes the mismatch case for when a VF
configures fewer queues than is allocated to it by the PF.

Anjali Singhai Jain 810b3ae42f i40e/i40evf: Ignore a driver perceived Tx hang if the number of desc pending < 4
We are seeing situations where the driver sees a hang with less than 4
desc pending, if the driver chooses to ignore it the queue progresses
forward and the stack never experiences a real hang.
With this patch we will log a stat when this situation happens
"tx_sluggish" will increment and we can see some more details
at a higher debug level. Other than that we will ignore this
particular case of Tx hang.

Shannon Nelson 30650cc552 i40e: quiet complaints when removing default MAC VLAN filter and make set_mac reversible
Older firmware has an incorrect MAC VLAN filter that needs to be replaced
at startup, and now newer firmware doesn't have this problem.  With this
change we no longer complain if the remove fails, and we only add the
new filter if the remove succeeded.

Setting a new LAA worked the first time, but didn't work well in successive
operations, including returning to the HW default address.  This simplifies
the code that was trying to be too smart.

Lastly, this pulls the hardware default mac address out into separate
handling code and keeps the broadcast filtering from getting munged.

Shannon Nelson f905dd62be i40e/i40evf: add max buf len to aq debug print helper
There is at least one case in the Firmware API where the response to a
command changes the buffer size field in the AQ descriptor to a larger
number than what the request's buffer size started as.  This is in addition
to setting an error flag and is in order to tell the requester how much
larger a buffer is required for the answer.  We need to be sure not to
use that number when dumping the contents of the data buffer because it
can send us into the weeds and generate an invalid pointer exception.

This patch adds a max buffer size parameter to the print helper to be
sure the code knows when to stop.

Anjali Singhai Jain 1e1be8f622 i40e: ATR policy change to flush the table to clean stale ATR rules
Instead of disabling ATR when we get a programming error, we now
will wait it out to see if some room gets created by ATR rule deletion.
If we still have too many errors and ATR filter count did not change
much, its time to flush and replay. We no more auto-disable ATR when
we have errors in programming.
The disabling of ATR when we get programming error was buggy and
was still adding new rules and causing continuous errors. With this
policy change we flush instead when we see too many errors.
ATR is still disabled if we add a SB rule for TCP/IPv4 flow type,
more logic is added to re-enable it once all SB TCP/IPv4 rules are gone.

Vlad Yasevich a12c415834 i40evf: Fix TSO and hw checksums for non-accelerated vlan packets.
This device claims TSO and checksum support for vlans.  It also
allows a user to control vlan acceleration offloading.  As such,
it is possible to turn off vlan acceleration and configure a vlan
which will continue to support TSO and hw checksums.

In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO and checksum information.
This results in corrupted frames sent on the wire.

This patch extract the protocol value correctly and corrects TSO
and checksums for non-accelerated traffic.

Fix this by using vlan_get_protocol() helper.

David S. Miller 0b725a2ca6 net: Remove ndo_xmit_flush netdev operation, use signalling instead.
As reported by Jesper Dangaard Brouer, for high packet rates the
overhead of having another indirect call in the TX path is
non-trivial.

There is the indirect call itself, and then there is all of the
reloading of the state to refetch the tail pointer value and
then write the device register.

Move to a more passive scheme, which requires very light modifications
to the device drivers.

The signal is a new skb->xmit_more value, if it is non-zero it means
that more SKBs are pending to be transmitted on the same queue as the
current SKB.  And therefore, the driver may elide the tail pointer
update.

Right now skb->xmit_more is always zero.

sends us an error in ARQ called LAN overflow event for a queue. We
check if the queue belongs to a VF and if it does we try to send a
vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled
we will be entering this function with a non-active VF id. In this

David Ertman 2116bc25e8 e1000e: Fix EEE in S5 w/ Runtime PM enabled
The process of shutting down the system causes a call to the close PM
callback.  The reset in close causes a loss of link, and the resultant
LSC interrupt causes the Runtime PM idle callback to be called.  The
check for link (while link is down) in the idle callback is wiping the
information about the EEE ability of the link partner.  The information is
still gone when the PHY is powered back up in the shutdown flow.  This
causes EEE in S5 to fail when Runtime PM is active.

Save the link partner's EEE ability in the idle callback so that a Runtime
PM event will not cause a loss of this information.

when link is up and disabled by the hardware when link is lost.

To enable EEE in Sx (When both ends of the link support, and are enabled
for, EEE and 100Mbps), we need to disable LPLU and configure the PHY to
automatically enable EEE when link is up, since there will be no software
to complete the task.

To configure this in the PHY, the Auto Enable LPI bit in the Low Power
Idle GPIO Control register must be set.  For normal operation in S0, this
bit must be cleared.

Reword the error messages. Also add a major version check because
We only want to warn on nvm_minor > expected_minor if
nvm_major == expected_major. Lastly, change an if to an else if
because the two statements will never evaluate to true at the same time.

Copy desc and buffer data even for ARQ events which return error status.
Previously, a check for NVM related AQ commands which is done later in this

not clear nvm_busy flag. This would block access to NVM until a driver reset.
This will fix that.

Jesse Brandeburg 22d2fa1d31 i40e/i40evf: fix extension header csum logic
The hardware design requires that the driver avoid indicating
checksum offload success on some ipv6 frames with extension
headers.

The code needs to just check for the IPV6EXADD bit and if
it is set punt the checksum to the stack.  I don't know why
the code was checking TCP on inner protocol, as that code
doesn't make any sense to me but seems wrong, so remove it.

Shannon Nelson cd552cb49e i40e/i40evf: Add nvmupdate support
This implements a state machine intended to support the userland tool for
updating the device eeprom. The state machine implements one-shot reads,
writes, multi-step write sessions, and checksum requests. If we're in the middle
of a multi-step write session, no one should fire off other writes, however, one
shot reads are valid. The userland tool is expected to keep track of its session
status, arrange the placement and ordering of the writes, and deal with the
checksum requirement.

This patch also adds nvmupdate support to ethtool callbacks.
The get_eeprom() and set_eeprom() services in ethtool are used here to
facilitate the userland NVMUpdate tool.  The 'magic' value in the get and
set commands is used to pass additional control information for managing
the read and write steps.

The read operation works both as normally expected in the standard ethtool
method, as well as with the extra NVM controls.  The write operation
works only for the expanded NVM functions - the normal ethtool method is
not allowed because of the NVM semaphore management needed for multipart
writes, as well as the checksum requirement.

This patch prevents the display of the minimum link qualification check
if we might be in a virtual machine. This check is incorrect and
misleading in this case, since we actually don't really know what the
available bandwidth is. To do so, we simply check whether each function
on the bus matches our device id. If it doesn't the most likely scenario
is that we're directly assigned to a virtual machine.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2014-07-16

This series contains updates to i40e only.

Neerav adds support to get the port MAC address from firmware and adds
support to the ndo_get_phys_port_id() callback to provide port specific
unique ids to the netdev layer.

Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software
time stamp if the hardware time stamp is provided.  Second fixes a race
condition on queueing skb for hardware time by using a simple bit lock to
avoid race conditions and leaking skbs when multiple transmit rings try
to claim time stamping.

Paul does some general cleanup of the driver to remove unneeded spaces,
comments that are no longer valid, and break that will never get touched.

Jacob Keller adds a verbose warning message when the incorrect PF attempts
to control timestamping for a port to which it was not assigned.  The primary
intent of this message is to help debugging the reason why the SIOCSHWSTAMP
ioctl has failed and to help narrow the cause of the issue.

This patch adds a new API to get the port mac address from firmware.

If the adapter has a valid per-port mac address then that
would be used for this purpose and is expected to be unique
on a per-port basis.

The information can be viewed by reading the phys_port_id
attribute in sysfs for each netdev or via IF netlink
interface.

Anjali Singhai Jain 49d7d93331 i40e/i40evf: Do not free the dummy packet buffer synchronously
The HW still needs to consume it and freeing it in the function
that created it would mean we will be racing with the HW. The
i40e_clean_tx_ring() routine will free up the buffer attached once
the HW has consumed it.  The clean_fdir_tx_irq function had to be fixed
to handle the freeing correctly.

Cases where we program more than one filter per flow (Ipv4), the
code had to be changed to allocate dummy buffer multiple times
since it will be freed by the clean routine.  This also fixes an issue
where the filter program routine was not checking if there were
descriptors available for programming a filter.

In some circumstances, the firmware could beat us to the punch, and the
reply from the PF would come back before we were able to properly modify
the aq_pending and aq_required flags. This would mess up the flags and
put the driver in an indeterminate state, much like Schrödinger's cat.
However, unlike the cat, the driver is definitely dead.

To fix this, simply set the flags before sending the request to the AQ.
This way, it won't matter if the interrupt comes back too soon.

Anjali Singhai Jain 129573883c i40e: Fix the FD sideband logic to detect a FD table full condition
Hardware does not have a way of telling a PF how much of the global
shared FD table space is still available or is consumed.
Previously, every PF but PF0 would think there was still space available
when there wasn't. The PFs would continue to try to add filters and fail.
With this new logic if a filter programming error is detected we just
check if we are close to the guaranteed space full and that can be used
as a hint to say, there might not be space and we should turn off the
features. This way we can turn off the feature in SW for all PFs in
time.

Jacob Keller fbd5e2df9f i40e: only create PTP device node once
Currently every time we run through the i40e_ptp_init routine, we create
a new device node. This function is called by i40e_reset_and_rebuild
which is used to handle reset of the device. Even though the 1588
registers only get cleared on a GLOBAL reset, this function is still
called to handle a CORE reset.

This causes a leak of PTP device nodes at every reset. To fix this,
break PTP device clock node creation out of i40e_ptp_init, and only call
this if we don't already have a device created. Further invocation of
i40e_ptp_init will not generate new PTP devices. Instead, only the
necessary work required to reconfigure 1588 will be done.

This change also fixes an issue where a reset can cause the
device to forget it's timestamp configuration, and revert to the default
mode.

Jacob Keller 189464555a i40e: break PTP hardware control from ioctl command for timestamp mode
This patch facilitates future work by breaking the PTP hardware control
bits out of the i40e_set_ts_config function. By doing this, we can
maintain state about the 1588 timestamping mode and properly re-enable
to the last known mode during a re-initialize of 1588 bits.

This patch also modifies i40e_ptp_init to call the
i40e_ptp_set_timestamp_mode during the reconfiguration process. A
future patch will ensure that the hwtstamp_config structure is not reset
during this process, so that timestamp mode will be maintained across a
reset.

Neerav Parikh df430b1240 i40e: Add PF reset when Malicious driver event for PF
As per the spec when the PF driver receives a Malicious driver event
the queue that caused the event is already stopped and it is expected
that the function that owns the queue will reset the queue.
In some cases it may not be possible to determine the queue and it is
suggested to reset the whole function.

This patch takes the later approach when the event is owned by the PF
that owns it.

make the function a void type.

Greg Rose 17413a80bc i40e: Stop the VF device after setting its MAC address
If the host VMM administrator has changed the VF device's MAC address then
the i40e driver needs to halt the VF device so that the administrator will
be forced to reload the VF driver.  This will cause the VF driver to start
using the newly assigned MAC address.  This brings the i40e driver into
conformance with operational characteristics of other Intel SR-IOV
featured drivers.

Jesse Brandeburg 8a3c91cce3 i40e/i40evf: add PPRS bit to error bits and fix bug in Rx checksum
The driver was not marking packets with bad checksums
correctly, especially IPv6 packets with a bad checksum.
To do this correctly we need a define that may be set by
hardware in rare cases.

The number of VSIs that the firmware reports to us is a guaranteed
minimum, not an absolute maximum. The hardware actually supports far
more  than the reported value, which we often need.

To allow for this, we allocate space for a larger number of VSIs than is
guaranteed by the firmware, with the knowledge that we may fail to get
them all in the future.

Note that we are just allocating pointers here, the actual (much larger)
VSI structures are allocated on demand.

have been broken now that the kernel can send as much as 32kB
in a single skb->frag[.] entry, even on a system with 4kB pages.

This fixes the assumptions and allows the kernel to operate
as efficiently as possible with both SENDFILE and SEND.

In addition, the hardware limit of data contained in a descriptor is
changed to the next power of two below where it currently is in
order to align to a power of two value, preventing a single byte
of data in a descriptor.

Mitch Williams 263fc48f97 i40e: notify VF of all types of resets
Currently, the PF driver only notifies the VFs for PF reset events.
Instead, notify the VFs for all types of resets, so they can attempt a
graceful reinit.

Mitch Williams d732a18445 i40evf: fix crash when changing ring sizes
i40evf_set_ringparam was broken in several ways. First, it only changed
the size of the first ring, and second, changing the ring size would
often result in a panic because it would change the count before
deallocating resources, causing the driver to either free nonexistent
buffers, or leak leftover buffers.

Fix this by storing the descriptor count in the adapter structure, and
updating the count for each ring each time we allocate them. This
ensures that we always free the right size ring, and always end up with
the requested count when the device is (re)opened.

The driver was already using VLAN_HLEN when setting the
hardware max receivable frame size, so just add it to the

Register range, being subject to register diagnostic, can vary among

a register test. This is needed to avoid false test results. If we fail
to define the proper register range we will test only the first register
from that group.

Emil Tantilov d9cd46cd39 ixgbe: fix detection of SFP+ capable interfaces
In cases where the driver is loaded while there are no SFP+ modules in
the cage the interface was not being detected as SFP capable. To account
for this the driver called identify_sfp in ixgbe_get_settings to make
sure the data is correct. However when there is no SFP+ module in the cage
the driver waits for the I2C reads to time out which can take more than a
second and will cause issues with tools (like net-snmp) that may poll
for that information.

This patch resolves the issue by identifying interfaces with no PHY
type set as SFP capable which allows the driver to detect the SFP module
when the interface is brought up. As result of this we can also remove the
identify_sfp call from ixgbe_get_settings.

v2: remove the 82599 specific check since we have 82598 devices that are SFP
capable.

====================
Pull request: Fixes for new ethtool RSS commands

This addresses several problems I previously identified with the new
ETHTOOL_{G,S}RSSH commands:

1. Missing validation of reserved parameters
2. Vague documentation
3. Use of unnamed magic number
4. No consolidation with existing driver operations

I don't currently have access to suitable network hardware, but have
tested these changes with a dummy driver that can support various
combinations of operations and sizes, together with (a) Debian's ethtool
3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH
and minor adjustment for fixes 1 and 3.

v2: Update RSS operations in vmxnet3 too

Shannon Nelson 7e612411e7 i40e: relax the firmware API version check
As long as the Firmware isn't reporting a higher API major version number
than what the driver knows about, the driver does not need to worry as
much about greater minor numbers.  The API changes minor numbers when
things get added to the API, but no existing structs or calls are changed.
The driver has the option of warning that the minor numbers don't match.

This will allow a little more flexibility in handling newer NICs and NVMs
in the field.
