"In the ARP case, when there's no other traffic on p54spi,

only ARP requests that match filter pass through.
In the multicast case filter seems to work correctly, but
it treats broadcast as subject to that filtering too. By
default only 01:00:5e:00:00:01 gets into priv->mc_maclist,
so we miss all broadcasts.
These two filters seem to interfere:
- if we set ARP filter and multicast filter without bc
=> we miss all ARPs if there's no egress traffic;
- if we set ARP filter and multicast filter with bc or
don't set mc filter at all => we get all ARPs.
This effect does not depend on filter setup order."

ath9k_hw: Fix Tx IQ Calibration hang issue in AR9003 chips
On AR9003 chips, doing three IQ calibrations will possibly cause chip
in stuck state. In noisy environment, chip could receive
a packet during the middle of three calibrations and it causes
the conflict of HW access and the eventual failure. It also
causes IQ calibration outliers which results in poor Tx EVM.
The IQ Cal procedure is after resetting the chip, run IQ cal 3 times
per each cal cycle and find the two closest readings and average of two.
The advantage of running Tx IQ cal more than once is that we can compare
calibration results for the same gain setting over multiple iterations.
Most of the cases the IQ failures were observed after first pass.
For the AR9485 and later chips, Tx IQ Calibration is performed along
with AGC cal. But for pre-AR9485 chips, Tx IQ cal HW has to be separated
from the rest of calibration HW to avoid chip hang. After all
calibrations are done in HW, we can start SW post-processing.
By doing this way, we minimize the SW difference among all chips.
The order of calibration (run IQ cal before other calibration) is also
needed to avoid chip hang for chips before AR9485. This issue was
originally observed with AR9382.
During the issue kernel log was filled with following message
ath: timeout (100000 us) on reg 0xa640: 0x00000001 & 0x00000001 != 0x00000000

This is in preparation to support life time expiry of packets in the
hardware to avoid head-of-line blocking where a slow client can
hog a tx queue and affect the traffic to a faster client from the same
queue. Time stamp the packets in driver to allow dropping them in the
hardware if they are queued for more than 500ms.
If queues are stopped, packets will be queued up outside the driver.
Since we will be able to timestamp the packets only after they hit the
driver, the timestamp will be less accurate since we cannot consider
the time the packets spent in queues outside the driver. With this commit,
to achieve accurate timestamping, the tx queues will not be stopped in
normal conditions. The only scenarios where the queues will be stopped are
when firmware commands are executing or if the interface is brought down.
Now, we need to be prepared for a situation where packets hit the driver
even after the tx queues are full. Drop all such packets in the driver itself.
