"boolean" converts a module dependency (MAC80211=m) to YES,
then the WL12XX driver can be built-in instead of only
modular, which leads to linker errors:

Replenishment of receive buffers is done in the tasklet handling
received frames as well as in a workqueue. When we are in the tasklet
we cannot sleep and thus attempt atomic skb allocations. It is generally
not a big problem if this fails since iwl_rx_allocate is always followed
by a call to iwl_rx_queue_restock which will queue the work to replenish
the buffers at a time when sleeping is allowed.
We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to
reduce the noise if such an allocation fails while we still have enough
buffers. We do maintain the warning and the error message when we are low
on buffers to communicate to the user that there is a potential problem with
memory availability on system
This addresses issue reported upstream in thread "iwlagn: order 2 page
allocation failures" in
http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187

commit 10c994ca70e8e94bbc85a5bf13de5911ee8de4d2 "iwlwifi: fix remove key
error" fixed an error reported by mac80211 during interface down. The fix
involved changing an async command to synchronous. Unfortunately this was
inside a spinlock section in which we cannot sleep.
Modify the sending of the command back to async. This causes the mac80211
error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from
hardware (-16)." to return. This error is not serious since this occurs
during interface down and the keys will be cleared anyway when ucode is
unloaded. Having this error message is thus less serious than a potential
deadlock introduced when sleeping while holding a spinlock. We will have to
find another fix for that error.
This is a revert of the abovementioned commit.

The current verison of b43 uses "b43_phyop_switch_analog_generic" for A,
G and LP phys.
According to the spec, this is the wrong behaviour for the LP PHY
(see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore )
While no problems on the x86 plattform where seen, this leads to a crash
on the BCM5354 SoC (MIPS 32 LE plattform).
This patch implements the analog switch for LP PHYs according to the
specs. It fixes the crash

There's a bug in 4965 powersave that appears to
be related to the way it keeps track of its data
during sleep, but we haven't found it yet. Due to
that, using powersave may spontaneously cause the
device to SYSASSERT when transitioning from sleep
to wake. Therefore, disable powersave for 4965,
until (if ever, unfortunately) we can identify
and fix the problem.
Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982

RX handling maintains a few lists that keep track of the RX buffers.
Buffers move from one list to the other as they are used, replenished, and
again made available for usage. In one such instance, when a buffer is used
it enters the "rx_used" list. When buffers are replenished an skb is
attached to the buffer and it is moved to the "rx_free" list. The problem
here is that the buffer is first removed from the "rx_used" list _before_ the
skb is allocated. Thus, if the skb allocation fails this buffer remains
removed from the "rx_used" list and is thus lost for future usage.
Fix this by first allocating the skb before trying to attach it to a list.
We add an additional check to not do this unnecessarily.

This fixes a resume failure where a signal is pending on resume
so the firmware upload fails.
This removes the interruptible sleep, because we don't really need it.
In the worst case (with broken firmware) the sleep loop will take 1 second.
In the common case (working firmware), it will only take a few milliseconds.
So we don't really need to be interruptible.

As the hostap driver was converted to use net_device_ops, a mistake was
made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5).
Originally, the tx_queue_len was set to 0 for every other interface than
HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to
0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous
behavior makes the driver to drop all packets in AP mode.
Change the way 0 is assigned to tx_queue_len according to the original
logic.
