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.

dp83640: use proper function to free transmit time stamping packets

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

commit f5ff7cd1a84caa9545d952a37ac872ccb73825fb upstream.

The previous commit enforces a new rule for handling the cloned packets
for transmit time stamping. These packets must not be freed using any other
function than skb_complete_tx_timestamp. This commit fixes the one and only
driver using this API.

The driver first appeared in v3.0.

tg3: fix tigon3_dma_hwbug_workaround()

2011-11-11T17:43:40+00:00

[ Upstream commit f7ff19871bb4a3451e1ca2cf660bf633018cfbec ]

Ari got kernel panics using tg3 NIC, and bisected to 2669069aacc9 "tg3:
enable transmit time stamping."

This is because tigon3_dma_hwbug_workaround() might alloc a new skb and
free the original. We panic when skb_tx_timestamp() is called on freed
skb.

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.

dp83640: free packet queues on remove

2011-11-11T17:43:06+00:00

commit 8b3408f8ee994973869d8ba32c5bf482bc4ddca4 upstream.

If the PHY should disappear (for example, on an USB Ethernet MAC), then
the driver would leak any undelivered time stamp packets. This commit
fixes the issue by calling the appropriate functions to free any packets
left in the transmit and receive queues.

The driver first appeared in v3.0.

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.
