ath9k: Fix a warning due to a queued work during S3 state

2011-05-10T19:46:58+00:00

during suspend/S3 state drv_flush is called from mac80211 irrespective of
interface count. In ath9k we queue a work in ath9k_flush which we expect
to be cancelled in the drv_stop call back. during suspend process mac80211
calls drv_stop only when the interface count(local->count) is non-zero.
unfortunately when the network manager is enabled, drv_flush is called
while drv_stop is not called as local->count reaches '0'.
	So fix this by simply checking for the device presence in the
drv_flush call back in the driver before queueing work or anything else.
this patch fixes the following WARNING

ath9k: fix the return value of ath_stoprecv

2011-04-19T19:22:52+00:00

The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect
a condition where rx DMA was stopped, but the MAC failed to enter the idle
state. This condition requires a hardware reset, however the return value
of ath_stoprecv was 'true' in that case, which allowed it to skip the reset
when issuing a fast channel change.

ath9k_htc: Fix ethtool reporting

2011-04-12T20:41:34+00:00

Pass the correct module name and device interface so that
ethtool can display the proper values.

The firmware version will be fixed later on when the FW
can actually report a version. :)

ath9k_hw: fix stopping rx DMA during resets

2011-04-12T20:41:33+00:00

During PHY errors, the MAC can sometimes fail to enter an idle state on older
hardware (before AR9380) after an rx stop has been requested.

This typically shows up in the kernel log with messages like these:

ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
------------[ cut here ]------------
WARNING: at drivers/net/wireless/ath/ath9k/recv.c:504 ath_stoprecv+0xcc/0xf0 [ath9k]()
Call Trace:
[<8023f0e8>] dump_stack+0x8/0x34
[<80075050>] warn_slowpath_common+0x78/0xa4
[<80075094>] warn_slowpath_null+0x18/0x24

[<80d642cc>] ath_set_channel+0xbc/0x270 [ath9k]
[<80d65254>] ath_radio_disable+0x4a4/0x7fc [ath9k]

When this happens, the state that the MAC enters is easy to identify and
does not result in bogus DMA traffic, however to ensure a working state
after a channel change, the hardware should still be reset.

This patch adds detection for this specific MAC state, after which the above
warnings completely disappear in my tests.

ath9k: fix missing ath9k_ps_wakeup/ath9k_ps_restore calls

2011-04-08T17:06:30+00:00

These missing chip wakeups mainly cause crashes on AR5416 cards in MIPS
boards, but have also been reported to cause radio stability issues on
AR9285.
