4f6760b01b ath9k: Fix tx throughput drops for AR9003 chips with AES encryption
While sending aggregated frames in AES, the AR5416 chips
required additional padding b/w subframes. This workaround
is not needed for edma (AR9003 family) chips. With this patch
~4Mbps thoughput improvement was observed in clear environment.

which is obviously wrong, the user should not see the *_UCODE_API_MAX
macros but the actual ucode API versions here.

The problem are the
    #define *_MODULE_FIRMWARE(api) *_FW_PRE #api ".ucode"
which do not expand api correctly (because this is a macro itself).

Fixed by using __stringify() from linux/stringify.h.

42b70a5f6d iwlagn: use cts-to-self protection on 5000 adapters series
This patch fixes 802.11n stability and performance regression we have
since 2.6.35. It boost performance on my 5GHz N-only network from about
5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.

These are test results of 5x downloading of approximately 700MB iso
image:

vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946

This was achieved with NetworkManager configured to do not perform
periodical scans, by configuring constant BSSID. With periodical scans,
after some time, performance downgrade to unpatched driver level, like
in example below:

patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683

However patch still make better here, since similar test on unpatched
driver make link disconnects with below messages after some time:

wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
wlan1: authentication with 00:23:69:35:d1:3f timed out

On 2.6.35 kernel patch helps against connection hangs with messages:

iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
iwlagn 0000:20:00.0: On demand firmware reload

d2ac49fe3c libertas_sdio: handle spurious interrupts
Commit 06e8935feb adds an IRQ handling
optimization for single-function SDIO cards like this one, but at the
same time exposes a small hardware bug.

During hardware init, an interrupt is generated with (apparently) no
source. Previously, mmc threw this interrupt away, but now (due to the
optimization), the mmc layer passes this onto libertas, before it is ready
(and before it has enabled interrupts), causing a crash.

Work around this hardware bug by registering the IRQ handler later and
making it capable of handling interrupts with no cause. The change that
makes the IRQ handler registration happen later actually eliminates
the spurious interrupt as well.

59342f6a6b zd1211rw: fix to work on OHCI
zd1211 devices register 'EP 4 OUT' endpoint as Interrupt type on USB 2.0:

      Endpoint Descriptor:
        bLength                 7
        bDescriptorType         5
        bEndpointAddress     0x04  EP 4 OUT
        bmAttributes            3
          Transfer Type            Interrupt
          Synch Type               None
          Usage Type               Data
        wMaxPacketSize     0x0040  1x 64 bytes
        bInterval               1

However on USB 1.1 endpoint becomes Bulk:

      Endpoint Descriptor:
        bLength                 7
        bDescriptorType         5
        bEndpointAddress     0x04  EP 4 OUT
        bmAttributes            2
          Transfer Type            Bulk
          Synch Type               None
          Usage Type               Data
        wMaxPacketSize     0x0040  1x 64 bytes
        bInterval               0

Commit 37939810b9 assumed that endpoint is
always interrupt type and changed usb_bulk_msg() calls to usb_interrupt_msg().

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the
call and changes requested pipe to interrupt type (see usb_bulk_msg).
However with usb_interrupt_msg() on bulk endpoint does not correct the
pipe type to bulk, but instead URB is submitted with interrupt type pipe.

So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint
types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes
ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw
from working with OHCI.

Fix this by detecting endpoint type and using correct endpoint/pipe types
for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right
URB type on 'EP 4 OUT'.

66870b1ccd wl12xx: fix oops in sched_scan when forcing a passive scan
Fix kernel oops when trying to use passive scheduled scans.  The
reason was that in passive scans there are no SSIDs, so there was a
NULL pointer dereference.

To solve the problem, we now check the number of SSIDs provided in the
sched_scan request and only access the list if there's one or more
(ie. passive scan is not forced).  We also force all the channels to
be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally
before the checks in the wl1271_scan_get_sched_scan_channels()
function.

50a66d7f04 wl12xx: add separate config value for DFS dwell time on sched scan
Use a different value for DFS dwell time when performing a scheduled
scan.  Previously we were using the same value as for normal passive
scans.  This adds some flexibility between these two different types
of passive scan.

For now we use 150 TUs for DFS channel dwell time.  This may need to
be fine-tuned in the future.

2497a246e8 wl12xx: fix DFS channels handling in scheduled scan
DFS channels were never getting included in the scheduled scans,
because they always contain the passive flag as well and the call was
asking for DFS and active channels.

Fix this by ignoring the passive flag when collecting DFS channels.
Also, move the DFS channels in the channel list before the 5GHz active
channels (this was implemented in the FW differently than specified).

71005be40a libertas: Set command sequence number later to ensure consistency
Before this patch, the command sequence number is being set before
lbs_queue_cmd() adds the command to the queue. However, lbs_queue_cmd()
sometimes forces commands to queue-jump (e.g. CMD_802_11_WAKEUP_CONFIRM).
It currently does this without considering that sequence numbers might need
adjusting to keep things running in order.

Fix this by setting the sequence number at a later stage, just before
we're actually submitting the command to the hardware. Also fixes a
possible race where seqnum was being modified outside of the driver
lock.

64bd0821a3 wireless: Default to 'n' for 2 new added devices in Kconfig.
We make oldconfig every time when a new kernel arrives, but
if we don't have such a device(I guess this is the most common
case for a new device), the default value should be 'n' so
that the kernel size we build doesn't grow up too much quickly.
For anyone who has the device, it is OK for them to turn it on
by themselves.
