Subject: ath9k_htc: Simplify TX URB management

This patch simplifies URB management for transmission,
by removing the 'FLUSH' variable (which is not needed,
since we can determine if the URB has been killed by
looking at the URB status), and also handling the STOP
case properly.

Subject: ath9k_htc: Handle device unplug properly

When the USB device has been unplugged, there is
no point in trying to send commands to the target.
Fix this by denying all WMI commands in such a case.

Subject: ath9k_htc: Process command data properly

When handling the REGIN callback, processing
the incoming data first should be the preferred
mode of operation. Allocation of a new SKB may fail,
in which case, the URB will not be resubmitted.

Subject: ath9k_htc: Fix WMI command race

My patch "ath9k_htc: Handle WMI timeouts properly" introduced
a race condition in WMI command processing. The last issued command
should be stored _before_ issuing a WMI command. Not doing this
would result in the WMI event IRQ dropping correct command responses
as invalid.

Fix this race by storing the command id correctly.

Subject: ath9k_htc: Really fix device hotunplug

All commands to the target are disabled when the device
is unplugged, but a normal module unload has to be
differentiated from this case, as we could still receive
data in the RX endpoint. Fix this by checking if the
device is attached or not.

Subject: ath9k_htc: Simplify RX IRQ handler

A bunch of validation and processing in the RX IRQ handler
can be moved to the RX tasklet. The IRQ handler is
already heavy, with the memory allocation for handling
stream mode. Also, a memcpy of 40 bytes for every packet
can be avoided in the handler.

Subject: ath9k_hw: use the configured power limit for AR9003

Since the new AR9003 EEPROM code does tune the card for the configured
tx power level, we need to fill in the correct power limits in the TPC
part of the DMA descriptor.

Subject: ath9k_hw: fix noisefloor timeout handling on AR9003

When the noisefloor calibration times out, do not load -50 into
the registers, since this might cause rx issues. Instead, leave
enough time for the noise floor calibration to complete until
the next check.

Subject: ath9k_hw: Fix TX interrupt mitigation settings

TX interrupt mitigation reduces the number of interrupts
by addressing several interrupt actions (AR_IMR_TXOK,
AR_IMR_TXDESC) all in one interrupt so when enabling
it discard setting the other interrupts.

Without this TX interrupt mitigation would actually
increase the number of interrupts two-fold. We still
leave TX interrupt mitigation disabled as it is still
being tested.

Subject: ath9k: Avoid corrupt frames being forwarded to mac80211.

If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate
with WEP or TKIP, eventhough the received frame may be a CRC failed
corrupted frame. If this bit is set, H/W obeys key type in keycache.
If it is not set and if the key type in keycache is neither open nor
AES, H/W forces key type to be open.  But bit 29 should be set to 1
for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.
