ath9k_htc: accept 1.x firmware newer than 1.3

2013-04-26T04:23:48+00:00

commit 319e7bd96aca64a478f3aad40711c928405b8b77 upstream.

Since the firmware has been open sourced, the minor version has been
bumped to 1.4 and the API/ABI will stay compatible across further 1.x
releases.

rt2x00: rt2x00pci_regbusy_read() - only print register access failure once

2013-04-12T16:18:10+00:00

commit 83589b30f1e1dc9898986293c9336b8ce1705dec upstream.

BugLink: http://bugs.launchpad.net/bugs/1128840

It appears that when this register read fails it never recovers, so
I think there is no need to repeat the same error message ad infinitum.

mwifiex: cancel cmd timer and free curr_cmd in shutdown process

2013-04-05T17:16:37+00:00

commit 084c7189acb3f969c855536166042e27f5dd703f upstream.

curr_cmd points to the command that is in processing or waiting
for its command response from firmware. If the function shutdown
happens to occur at this time we should cancel the cmd timer and
put the command back to free queue.

b43: A fix for DMA transmission sequence errors

2013-04-05T17:16:36+00:00

commit b251412db99ccd4495ce372fec7daee27bf06923 upstream.

Intermittently, b43 will report "Out of order TX status report on DMA ring".
When this happens, the driver must be reset before communication can resume.
The cause of the problem is believed to be an error in the closed-source
firmware; however, all versions of the firmware are affected.

This change uses the observation that the expected status is always 2 less
than the observed value, and supplies a fake status report to skip one
header/data pair.

Not all devices suffer from this problem, but it can occur several times
per second under heavy load. As each occurence kills the unmodified driver,
this patch makes if possible for the affected devices to function. The patch
logs only the first instance of the reset operation to prevent spamming
the logs.

rt2x00: error in configurations with mesh support disabled

2013-03-28T19:06:14+00:00

commit 6ef9e2f6d12ce9e2120916804d2ddd46b954a70b upstream.

If CONFIG_MAC80211_MESH is not set, cfg80211 will now allow advertising
interface combinations with NL80211_IFTYPE_MESH_POINT present.
Add appropriate ifdefs to avoid running into errors.

[Backported for 3.8-stable. Removed code of simultaneous AP and mesh
mode added in 4a5fc6d 3.9-rc1.]

ath9k: fix RSSI dummy marker value

2013-03-14T18:32:05+00:00

commit a3d63cadbad97671d740a9698acc2c95d1ca6e79 upstream.

RSSI is being stored internally as s8 in several places. The indication
of an unset RSSI value, ATH_RSSI_DUMMY_MARKER, was supposed to have been
set to 127, but ended up being set to 0x127 because of a code cleanup
mistake. This could lead to invalid signal strength values in a few
places.

commit 008e33f733ca51acb2dd9d88ea878693b04d1d2a upstream.

Corrected USB ID for T-Com Sinus 154 data II. ISL3887-based. The
device was tested in managed mode with no security, WEP 128
bit and WPA-PSK (TKIP) with firmware 2.13.1.0.lm87.arm (md5sum:
7d676323ac60d6e1a3b6d61e8c528248). It works.

commit 0a06ad8e3a1cb5311b7dbafde45410aa1bce9d40 upstream.

In routine _rtl_rx_pre_process(), skb_dequeue() is called to get an skb;
however, the wrong variable name is used in subsequent calls.
