Below EST errors are added into ethtool statistic:
1) Constant Gate Control Error (CGCE):
The counter "mtl_est_cgce" increases everytime CGCE interrupt is
triggered.
2) Head-of-Line Blocking due to Scheduling (HLBS):
The counter "mtl_est_hlbs" increases everytime HLBS interrupt is
triggered.
3) Head-of-Line Blocking due to Frame Size (HLBF):
The counter "mtl_est_hlbf" increases everytime HLBF interrupt is
triggered.
4) Base Time Register error (BTRE):
The counter "mtl_est_btre" increases everytime BTRE interrupt is
triggered but BTRL not reaches maximum value of 15.
5) Base Time Register Error Loop Count (BTRL) reaches maximum value:
The counter "mtl_est_btrlm" increases everytime BTRE interrupt is
triggered and BTRL value reaches maximum value of 15.

====================
Add tc hardware offloads
This patch series adds support for tc hardware offloads.
Patch #1 adds support for offloading flows that matches IP tos and IP
protocol which will be used by tc hw offload support. Also
added ethtool n-tuple filter to code to offload the flows
matching the above fields.
Patch #2 adds tc flower hardware offload support on ingress traffic.
Patch #3 adds TC flower offload stats.
Patch #4 adds tc TC_MATCHALL egress ratelimiting offload.
* tc flower hardware offload in PF driver
The driver parses the flow match fields and actions received from the tc
subsystem and adds/delete MCAM rules for the same. Each flow contains set
of match and action fields. If the action or fields are not supported,
the rule cannot be offloaded to hardware. The tc uses same set of MCAM
rules allocated for ethtool n-tuple filters. So, at a time only one entity
can offload the flows to hardware, they're made mutually exclusive in the
driver.
Following match and actions are supported.
Match: Eth dst_mac, EtherType, 802.1Q {vlan_id,vlan_prio}, vlan EtherType,
IP proto {tcp,udp,sctp,icmp,icmp6}, IPv4 tos, IPv4{dst_ip,src_ip},
L4 proto {dst_port|src_port number}.
Actions: drop, accept, vlan pop, redirect to another port on the device.
The Hardware stats are also supported. Currently only packet counter stats
are updated.
* tc egress rate limiting support
Added TC-MATCHALL classifier offload with police action applied for all
egress traffic on the specified interface.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

$ tc qdisc add dev eth0 clsact
$ tc filter add dev eth0 egress matchall skip_sw \
action police rate 100Mbit burst 16Kbit

This patch adds support for tc flower hardware offload on ingress
traffic. Since the tc-flower filter rules use the same set of MCAM
rules as the n-tuple filters, the n-tuple filters and tc flower
rules are mutually exclusive. When one of the feature is enabled
using ethtool, the other feature is disabled in the driver. By default
the driver enables n-tuple filters during initialization.
The following flow keys are supported.
-> Ethernet: dst_mac
-> L2 proto: all protocols
-> VLAN (802.1q): vlan_id/vlan_prio
-> IPv4: dst_ip/src_ip/ip_proto{tcp|udp|sctp|icmp}/ip_tos
-> IPv6: ip_proto{icmpv6}
-> L4(tcp/udp/sctp): dst_port/src_port
The following flow actions are supported.
-> drop
-> accept
-> redirect
-> vlan pop
The flow action supports multiple actions when vlan pop is specified
as the first action. The redirect action supports redirecting to the
PF/VF of same PCI device. Redirecting to other PCI NIX devices is not
supported.
Example #1: Add a tc filter rule to drop UDP traffic with dest port 80
# ethtool -K eth0 hw-tc-offload on
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 protocol ip parent ffff: flower ip_proto \
udp dst_port 80 action drop
Example #2: Add a tc filter rule to redirect ingress traffic on eth0
with vlan id 3 to eth6 (ex: eth0 vf0) after stripping the vlan hdr.
# ethtool -K eth0 hw-tc-offload on
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 parent ffff: protocol 802.1Q flower \
vlan_id 3 vlan_ethtype ipv4 action vlan pop action mirred \
ingress redirect dev eth6
Example #3: List the ingress filter rules
# tc -s filter show dev eth4 ingress
Example #4: Delete tc flower filter rule with handle 0x1
# tc filter del dev eth0 ingress protocol ip pref 49152 \
handle 1 flower

The ethtool n-tuple filter logic has been updated to parse the IP tos

supported. See example usage below.
Ex: Redirect l4proto icmp to vf 0 queue 0

Add support for mv88e6393x family of Marvell
after 2 months I finally had time to send v17 of Amethyst patches.
This series is tested on Marvell CN9130-CRB.
Changes since v16:
- dropped patches adding 5gbase-r, since they are already merged
- rebased onto net-next/master
- driver API renamed set_egress_flood() method into 2 methods for
ucast/mcast floods, so this is fixed
Changes from v15:
- put 10000baseKR_Full back into phylink_validate method for Amethyst,
it seems I misunderstood the meaning behind things and removed it
from v15
- removed erratum 3.7, since the procedure is done anyway in
mv88e6390_serdes_pcs_config
- renumbered errata 3.6 and 3.8 to 4.6 and 4.8, according to newer
version of the errata document
- refactored errata code a little and removed duplicate macro
definitions (for example MV88E6390_SGMII_CONTROL is already called
MV88E6390_SGMII_BMCR)
Changes from v14:
- added my Signed-off-by tags to Pavana's patches, since I am sending
them (as suggested by Andrew)
- added documentation to second patch adding 5gbase-r mode (as requested
by Russell)
- added Reviewed-by tags
- applied Vladimir's suggestions:
- reduced indentation level in mv88e6xxx_set_egress_port and
mv88e6393x_serdes_port_config
- removed 10000baseKR_Full from mv88e6393x_phylink_validate
- removed PHY_INTERFACE_MODE_10GKR from mv88e6xxx_port_set_cmode
Changes from v13:
- added patch that wraps .set_egress_port into mv88e6xxx_set_egress_port,
so that we do not have to set chip->*gress_dest_port members in every
implementation of this method
- for the patch that adds Amethyst support:
- added more information into commit message
- added these methods for mv88e6393x_ops:
.port_sync_link
.port_setup_message_port
.port_max_speed_mode (new implementation needed)
.atu_get_hash
.atu_set_hash
.serdes_pcs_config
.serdes_pcs_an_restart
.serdes_pcs_link_up
- this device can set upstream port per port, so implement
.port_set_upstream_port
instead of
.set_cpu_port
- removed USXGMII cmode (not yet supported, working on it)
- added debug messages into mv88e6393x_port_set_speed_duplex
- added Amethyst errata 4.5 (EEE should be disabled on SERDES ports)
- fixed 5gbase-r serdes configuration and interrupt handling
- refactored mv88e6393x_serdes_setup_errata
- refactored mv88e6393x_port_policy_write
- added patch implementing .port_set_policy for Amethyst

The 16-bit Port Policy CTL register from older chips is on 6393x changed
to Port Policy MGMT CTL, which can access more data, but indirectly and
via 8-bit registers.
The original 16-bit value is divided into first two 8-bit register in
the Port Policy MGMT CTL.
We can therefore use the previous code to compute the mask and shift,
and then
- if 0 <= shift < 8, we access register 0 in Port Policy MGMT CTL
- if 8 <= shift < 16, we access register 1 in Port Policy MGMT CTL
There are in fact other possible policy settings for Amethyst which
could be added here, but this can be done in the future.

The Marvell 88E6393X device is a single-chip integration of a 11-port
Ethernet switch with eight integrated Gigabit Ethernet (GbE)
transceivers and three 10-Gigabit interfaces.
This patch adds functionalities specific to mv88e6393x family (88E6393X,
88E6193X and 88E6191X).
The main differences between previous devices and this one are:
- port 0 can be a SERDES port
- all SERDESes are one-lane, eg. no XAUI nor RXAUI
- on the other hand the SERDESes can do USXGMII, 10GBASER and 5GBASER
(on 6191X only one SERDES is capable of more than 1g; USXGMII is not
yet supported with this change)
- Port Policy CTL register is changed to Port Policy MGMT CTL register,
via which several more registers can be accessed indirectly
- egress monitor port is configured differently
- ingress monitor/CPU/mirror ports are configured differently and can be
configured per port (ie. each port can have different ingress monitor
port, for example)
- port speed AltBit works differently than previously
- PHY registers can be also accessed via MDIO address 0x18 and 0x19
(on previous devices they could be accessed only via Global 2 offsets
0x18 and 0x19, which means two indirections; this feature is not yet
leveraged with thiis commit)

updated instead of creating new rule. This way only one
mcam_rule exists for the only one default unicast entry

mlxsw: Allow 802.1d and .1ad VxLAN bridges to coexist on Spectrum>=2
Ido Schimmel says:
====================
This patchset allows user space to simultaneously configure both 802.1d
and 802.1ad VxLAN bridges on Spectrum-2 and later ASICs. 802.1ad VxLAN
bridges are still forbidden on Spectrum-1.
The reason for the current limitation is that up until now the EtherType
that was pushed to decapsulated VxLAN packets was a property of the
tunnel port, of which there is only one. This meant that a 802.1ad VxLAN
bridge could not be configured if the tunnel port was already configured
to push a 802.1q tag.
This patchset improves the situation by making two changes. First,
decapsulated packets are marked as having their EtherType decided by the
egress port. Second, local ports member in the bridge (e.g., swp1) are
configured to set the correct egress EtherType.
Patchset overview:
Patch #1 adds a register required for the first change
Patches #2-#3 add the register required for the second change and a
corresponding API
Patch #4 prepares the driver for the split in behavior between
Spectrum-1 and later ASICs
Patch #5 performs the two above mentioned changes to allow the driver to
support simultaneous 802.1ad and 802.1d VxLAN bridges on Spectrum-2 and
later ASICs
Patch #6 adds a selftest
Patch #7 removes a selftest that verified the limitation that was lifted

Currently only one EtherType can be configured for pushing in tunnels
because EtherType is configured using SPVID.et_vlan for tunnel port.
This behavior is forbidden by comparing mlxsw_sp_nve_config struct for
each new tunnel, the struct contains 'ethertype' field which means that
only one EtherType is legal at any given time. Remove 'ethertype' field to
allow creating VxLAN devices with different bridges.
To allow using several types of VxLAN bridges at the same time, the
EtherType should be determined at the egress port. This behavior is
achieved by setting SPVID to decide which EtherType to push at egress and
for each local_port which is member in 802.1ad bridge, set SPEVET.et_vlan
to ether_type1 (i.e., 0x88A8).
Use switchdev_ops->init() to set different mlxsw_sp_bridge_ops for
different ASICs in order to be able to split the behavior when port joins /

SPVID.egr_et_set=1 means that when VLAN is pushed at ingress (for untagged
packets or for QinQ push mode) then the EtherType is decided at the egress
port.
The next patches will use this field for VxLAN devices (tunnel port) in
order to allow using dual VxLAN bridges (802.1d and 802.1ad at the same
time).

We move some warning printouts to more strategic locations to avoid
duplicates and yield more detailed information about the reported
problem.

corresponding member, with fields set in host-endian format, to struct
tipc_subscription.
