b43: refuse to load unsupported firmware

2011-11-21T22:35:24+00:00

[This patch is supposed to be applied in 3.1 (and maybe older) branches only.]

New kernels support newer firmware that users may try to incorrectly use
with older kernels. Display error and explain the problem in such a case

ath9k_hw: Fix regression of register offset for AR9003 chips

2011-11-11T17:44:48+00:00

commit 52d6d4ef5e6d1517688e27c11c01ab303ec681dd upstream.

My recent commits (3782c69d, 324c74a) introduced regression
for register offset selection that based on the macversion.
Not using parentheses in proper manner for ternary operator
leads to select wrong offset for the registers.

This issue was observed with AR9462 chip that immediate disconnect
after the association with the following message

ieee80211 phy3: wlan0: Failed to send nullfunc to AP 00:23:69:12:ea:47
after 500ms, disconnecting.

iwlagn: do not use interruptible waits

2011-11-11T17:43:34+00:00

commit effd4d9aece9184f526e6556786a94d335e38b71 upstream.

Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.

This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.

Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.

This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'

I have seen in P2P testing, but it is likely
that there are other errors caused by this.

wl12xx: fix forced passive scans

2011-11-11T17:43:09+00:00

commit 6cd9d21a0c1e2648c07c32c66bb25795ad3208aa upstream.

We were using incorrect max and min dwell times during forced passive
scans because we were still using the active scan states to scan
(passively) the channels that were not marked as passive.

Instead of doing passive scans in active states, we now skip active
states and scan for all channels in passive states.

ath9k: disable unnecessary PHY error reporting

2011-11-11T17:42:44+00:00

commit ac06697c79bad09e44a8b1d52104014016fb90de upstream.

PHY errors relevant for ANI are always tracked by hardware counters, the
bits that allow them to pass through the rx filter are independent of that.
Enabling PHY errors in the rx filter often creates lots of useless DMA traffic
and might be responsible for some of the rx dma stop failure warnings.

ath9k_hw: Fix number of GPIO pins for AR9287/9300

2011-11-11T17:42:44+00:00

commit 6321eb0977b011ac61dfca36e7c69b2c4325b104 upstream.

this patch fixes the assumption of maximum number of GPIO pins present
in AR9287/AR9300. this fix is essential as we might encounter some
functionality issues involved in accessing the status of GPIO pins which
are all incorrectly assumed to be not within the range of max_num_gpio
of AR9300/AR9287 chipsets

ath9k_hw: Fix magnitude/phase coeff correction

2011-11-11T17:42:42+00:00

commit e9c10469cf3c71bc1c6b0f01319161e277d6ac9b upstream.

Do the magnitude/phase coeff correction only if the outlier
is detected. Updating wrong magnitude/phase coeff factor
impacts not only tx gain setting but also leads to poor
performance in congested networks. In the clear environment
the impact is very minimal because the outlier happens
very rarely according to the past experiment. It occured
less than once every 1000 calibrations.
