Add support to iwlagn for off-channel TX. The
microcode API for this is a bit strange in that
it uses a hacked-up scan command, so the scan
code needs to change quite a bit to accomodate
that and be able to send it out.

defs.meshie.val.mesh_id is 32 chars long. It's not supposed to be NUL
terminated. This code puts a terminator on the end to make it easier to
print to sysfs. The problem is that if the mesh_id fills the entire
buffer the original code puts the terminator one spot past the end.
The way the original code was written, there was a check to make sure
that maxlen was less than PAGE_SIZE. Since we know that maxlen is at
most 34 chars, I just removed the check.

The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad
and covers even frames with PHY errors. When this flag is enabled, this message
shows up frequently during scanning or hardware resets:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
Since promiscuous mode is usually not particularly useful, yet enabled by
default by bridging (either used normally in 4-addr mode, or with hacks
for various virtualization software), we should sacrifice it for better
reliability during normal operation.
This patch leaves it enabled if there are active monitor mode interfaces, since
it's very useful for debugging.

While working on PS I've noticed elp_work is kicking rather often, and
sometimes the chip is put to sleep before 5ms delay expires. This
seems to happen because by the time wl1251_ps_elp_wakeup is called
elp_work might still be pending. After wakeup is done, the processing
may take some time, during which 5ms might expire and elp_work might
get scheduled. In this case, ss soon as 1st thread finishes work and
releases the mutex, elp_work will then put the device to sleep without
5ms delay. In addition 1st thread will queue additional elp_work
needlessly.
Fix this by cancelling work in wl1251_ps_elp_wakeup instead.

wl1251_ps_set_elp() only does acx_sleep_auth call and takes the chip
from/to ELP, however all callers of wl1251_ps_set_mode() have already
taken the chip out of ELP and puts it back to ELP when they finish.
This makes ELP calls (and register writes they result in) superfluous.
So remove wl1251_ps_set_elp function and call acx_sleep_auth directly.

Filter "bad" (i.e. truncated) packets.
Avoid corrupting "dev->napi_list", by sequentializing modifications.
Deregister for incoming packets during stop, to reduce unexpected

Free any pending completions after shutting down LEPP.
Use a single, permanently registered, IRQ handler, to avoid situations
in which the IRQ handler was firing after being freed, and ignore any
"unexpected" interrupts.

The original code does not work well when the number of mulitcast
address to handle is greater than MCAST_MAX. It only enable promiscous
mode instead of multicast hash table mode, so the hash table function
will not be activated and all multicast frames will be recieved in this
condition.
This patch fixes the following issues with the r6040 NIC operating in
multicast:
1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC
hash table registers to make it process multicast traffic.
2) When the number of multicast address to handle is smaller than
MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}.
3) The hashing of the address was not correct, due to an invalid
substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an
incorrect crc algorithm (ether_crc_le) instead of (ether_crc).
4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast
hash table function.
