b43: Fix rxheader channel parsing

2008-01-09T07:30:06+00:00

This patch fixes the parsing of the RX data header channel field.

The current code parses the header incorrectly and passes a wrong
channel number and frequency for each frame to mac80211.
The FIXMEs added by this patch don't matter for now as the code
where they live won't get executed anyway. They will be fixed later.

b43: Fix rfkill radio LED

2007-12-17T22:01:40+00:00

This fixes Bug #9414

Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:

(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.

Once the above problems were fixed, additional difficulties were noted:

(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.

This patch fixes all of the above.

b43: properly request pcmcia IRQ

2007-11-10T09:25:13+00:00

PCMCIA needs an additional step to request the IRQ.

No need to add code to release the IRQ here, as that's done
automatically in pcmcia_disable_device().

b43: fix shared IRQ race condition

2007-11-10T09:25:13+00:00

Fix an IRQ race condition in b43. If we call b43_stop_wireless_core(), it
will set the status of the device to INITIALIZED and the IRQ handler won't
care any longer about IRQs, thus the kernel will disable the IRQ if it's
shared (unless we boot it with the 'irqpoll' option). So we must disable
IRQs before changing the device status.

b43: Rewrite and fix rfkill init

2007-11-10T09:25:12+00:00

The rfkill subsystem doesn't like code like that
rfkill_allocate();
rfkill_register();
rfkill_unregister();
rfkill_register(); /* <- This will crash */

This sequence happens with
modprobe b43
ifconfig wlanX up
ifconfig wlanX down
ifconfig wlanX up

Fix this by always re-allocating the rfkill stuff before register.
