Rishi Panjwani bc48ad31c5 ath6kl: Support for TCP checksum offload to firmware
The change enables offloading TCP checksum calculation to firmware.
There are still some issues with the checksum offload so better to
disable it by default until the issues are resolved.

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

To disable TCP checksum offload, for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx off
ethtool -K <interface> rx off

Kalle Valo 65a8b4cc51 ath6kl: add support for FW API 3
As firmware starting from 3.2.0.12 has some API changes and doesn't work
with older versions of ath6kl we need to bump up the API version. This
way we don't break anything.

Kalle Valo c0038972b1 ath6kl: handle firmware names more dynamically
Currently ath6kl has just hardcoded paths to each firmware file. Change
this more dynamic by separating the the directory and file name from each
other. That way it's easier to dynamically create full paths to firmware and
code looks better. And now it's possible to remove a function needed by
devicetree code.

While at it add a structure inside struct ath6kl_hw to contain all
firmware names. I deliberately omitted board file support as
those will be handled later.

This is needed for firmware API 3.

Aarthi Thiruvengadam 3ca9d1fc9a ath6kl: support for P2P mgmt operations on station interface
This patch enables support for doing P2P management operations like device
discovery on top of a station interface. After group formation, the station
interface will become a P2P GO/client interface as the case may be.

This feature requires modifications to a couple of existing WMI structures and
therefore new command ids and structures have been defined in order to be
compatible with older firmware versions and other chips. The exception here is
the wmi_connect_cmd. Adding a new field to the end of the structure will not
cause any issues with previous firmware versions since firmware only checks for
minimum length of the command. The other structures are of variable length,
hence it was not possible to add new fields to the end.

The new command ids have to be added to the end of enum wmi_cmd_id, so it has
updated to match the firmware.

The driver will support both the 'old' and the 'new' commands for a while by
checking the firmware capabilities.

change_virtual_intf() returns with no error, but there is a
check in this callback which does the type change only when
that interface is active. This callback does nothing more
than saving the new interface type to vif and wdev, so the
sanity check for interface state and wmi state is not necessary.

The firmware expects the minimum length of
WMI_SEND_PROBE_RESPONSE_CMDID to be 13. However, when the device is a
P2P GO and it needs to send a probe response to a non-P2P client,
there are no P2P IEs to be added, and therefore the length of the WMI
command is 12. This command gets rejected by the firmware. To fix
this, add an extra byte to satisfy the minimum length requirement.

"ath6kl: Maintain virtual interface in a list" mistakenly stops the

Jouni reported that my patch "ath6kl: power down hardware when interface

So there has to be a race condition somewhere in the code and disable the

point where module is loaded until it's removed.

Vasanthakumar Thiagarajan 11f6e40d9f ath6kl: Fix lockdep warning
The following is the lockdep warning which detects possible
deadlock condition with the way ar->lock and ar->list_lock
are being used.

  (&(&ar->lock)->rlock){+.-...}, at: [<ffffffffa0492d13>] ath6kl_indicate_tx_activity+0x83/0x110 [ath6kl]
 but this lock took another, SOFTIRQ-unsafe lock in the past:
  (&(&ar->list_lock)->rlock){+.+...}

 and interrupts could create inverse lock ordering between them.

 other info that might help us debug this:
  Possible interrupt unsafe locking scenario:

        CPU0                    CPU1
        ----                    ----
   lock(&(&ar->list_lock)->rlock);
                                local_irq_disable();
                                lock(&(&ar->lock)->rlock);
                                lock(&(&ar->list_lock)->rlock);
   <Interrupt>
     lock(&(&ar->lock)->rlock);

  *** DEADLOCK ***

softirqs have to be disabled when acquiring ar->list_lock to avoid
the above deadlock condition. When the above warning printed the
interface is still up and running without issue.

Currently it takes an error code as status, but what we really want to
tell is if the scan was aborted or not.

Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success
status code and checking for that.

Even though only a single concurrent remain-on-channel operation is
supported, there may be two pending remain-on-channel events (one to
indicate end of a canceled operation and another to indicate start of a
new operation). User space won't be able to distinguish these events
unless unique cookies are used.

The previous behavior resulted in wpa_supplicant getting quite
confused about the driver's offchannel state in various sequences
and this made the P2P state machine behave incorrectly. Use of
more than a single remain-on-channel cookie value fixes this.

The feature has been added for testing purposes. All 5 parameters are

file. These are:

1) idle_period
2) no_of_pspoll

The user has to write the listen interval_time (in msecs) and
listen_interval_beacons (in no. of beacons) to the listen_interval file in

Rishi Panjwani 116b3a2e0f ath6kl: Implement support for background scan control from userspace
In order to allow user space based control of background scan interval,
we use available debugfs infrastructure. The feature has been added for
testing purposes. The user has to write the bgscan interval (in secs) to
the bgscan_interval file in ath6kl debug directory. To disable bgscan,
a '0' is to be written to the bgscan_interval file.

Example:

echo "2" > bgscan_interval

This will make the background scan interval as 2 seconds

Rishi Panjwani 8fffd9e5ec ath6kl: Implement support for QOS-enable and QOS-disable from userspace
In order to allow user space based QOS control we use the available debugfs
infrastructure. With this feature, user can make changes to qos parameters,
thereby allowing creation and deletion of user defined priority streams and
features like uapsd. This feature has been added for testing purposes.

All 21 parameters for the create_qos command are mandatory in the correct
order. They have to be written to the create_qos file in
the ath6kl debug directory. These parameters(in order) are:

1)user priority
2)direction
3)traffic class
4)traffic type
5)voice PS capability
6)min service intvl
7)max service intvl
8)inactivity intvl
9)suspension intvl
10)serv start time
11)tsid
12)nominal msdu
13)max msdu
14)min data rate
15)mean data rate
16)peak data rate
17)max burst size
18)delay bound
19)min phy rate
20)surplus bw allowance
21)medium time

To create a qos stream:

echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000
56789000 5678900 0 0 9999999 20000 0" > create_qos

delete_qos requires 2 parameters:

1)traffic class
2)tsid

To delete a qos stream:

echo "3 1" > delete_qos

Joe Perches b9075fa968 treewide: use __printf not __attribute__((format(printf,...)))
Standardize the style for compiler based printf format verification.
Standardized the location of __printf too.

Done via script and a little typing.

$ grep -rPl --include=*.[ch] -w "__attribute__" * | \
  grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
  xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

Paul Gortmaker 6eb07caf1a drivers/net: Add moduleparam.h to drivers as required.
These files were using moduleparam infrastructure, but were not
including anything for it -- which is fine when module.h is being
implicitly included in all files, but that is going away.

Paul Gortmaker ee40fa0656 drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULE
These were getting the macros from an implicit module.h
include via device.h, but we are planning to clean that up.

drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c

This relatively recently added file uses EXPORT_SYMBOL and hence
needs export.h included so that it is compatible with the module.h
split up work.

Paul Gortmaker 9d9779e723 drivers/net: Add module.h to drivers who were implicitly using it
The device.h header was including module.h, making it present for
most of these drivers.  But we want to clean that up.  Call out the
include of module.h in the modular network drivers.
