ath9k: disable MIB interrupts to fix interrupt storm

2008-09-24T19:55:24+00:00

Enabling the MIB interrupts has proven to cause an
interrupt storm after 7 hours of run. We will make use of the
MIB interrupt once we have ANI supported added so for now
to cure this we disable the interrupt.

The interrupt storm can be seen as follows after 7 hours of run
as reported by  Steven Noonan :

18:28:38          sum   1106.00
18:28:39          sum   1037.62
18:28:40          sum   1069.00
18:28:41          sum   1167.00
18:28:42          sum   1155.00
18:28:43          sum   1339.00
18:28:44          sum  18355.00
18:28:45          sum  17845.45
18:28:46          sum  15285.00
18:28:47          sum  17511.00
18:28:48          sum  17568.69
18:28:49          sum  17704.04
18:28:50          sum  18566.67
18:28:51          sum  18913.13

at 18:28:44 the MIB interrupt kicked off and caused huge
latency which can be seen even on a video he submitted:

ath9k: Fix IRQ nobody cared issue with ath9k

2008-09-22T21:22:15+00:00

IRQs should be disabled before calling free_irq. Also flush pending
IRQs. Pasted the kernel log message for reference.

wireless: zd1211rw: add device ID fix wifi dongle "trust nw-3100"

2008-09-22T20:52:51+00:00

akpm: taken from http://bugzilla.kernel.org/show_bug.cgi?id=11587

I bought the wifi dongle trust nw-3100 wich is in fact a zd1211rw.  Its
hardware id was missing in the sources, adding it made it work flawlessly.

ath9k: connectivity is lost after Group rekeying is done

2008-09-22T20:52:50+00:00

Connectivtiy is lost after Group rekeying is done. The keytype
maintained by ath9k is reset when group key is updated. Though
sc_keytype can be reset only for broadcast key the proper fix
would be to use mac80211 provided key type from txinfo during
xmit and get rid of sc_keytype from ath9k ath_softc.

Revert "b43/b43legacy: add RFKILL_STATE_HARD_BLOCKED support"

2008-09-17T02:32:30+00:00

This reverts commit bc19d6e0b74ef03a3baf035412c95192b54dfc6f, which as
Larry Finger reports causes the radio LED on his system to no longer
respond to rfkill switch events.

ath9k: Assign seq# when mac80211 requests this

2008-09-11T15:10:28+00:00

Use TX control flag IEEE80211_TX_CTL_ASSIGN_SEQ as a request to update
the seq# for the frames. This will likely require some further cleanup
to get seq# correctly for Beacons vs. other frames and also potentially
for multiple BSSes. Anyway, this is better than ending up sending out
most frames with seq# 0.

(This is a backport of patch w/ same title already in net-next-2.6.
It is verified to fix http://bugzilla.kernel.org/show_bug.cgi?id=11394
and it should be acceptable for -rc due to the driver being new
in 2.6.27.)
