The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.
The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.
The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.
This makes new uCode work on 6000 series devices.

Noise floor calibration does not interfere with traffic and should run more
often as part of our "short calibration". The full calibration is not the
noise floor calibration but the AGC + Gain_F (on RF5111 and RF5112) calibration
and should run less often because it does interfere with traffic.
So
Short calibration -> I/Q & NF Calibration
Long calibration -> Short + AGC + Gain_F
This patch was for some time on my pub/ dir on www.kernel.org and has been tested

Signed-off-by: John W. Linville <linville@tuxdriver.com>
Since card has 12 tx queues and we want to keep track of the interrupts
per queue we can't fit all these interrupt bits on a single register.
So we have 5 registers, the primary interrupt status register (PISR) and
the 4 secondary interupt status registers (SISRs).
In order to be able to read them all at once (atomic operation) Atheros
introduced the Read-And-Clear registers to make things easier. So when
reading RAC_PISR register, hw does a read on PISR and all SISRs, returns
the value of PISR, copies all SISR values to their shadow copies (RAC_SISRx)
and clears PISR and SISRs. This saves us from reading PISR/SISRs in a sequence.
So far we 've used this approach and MadWiFi/Windows driver etc also used it
for years.
It turns out this operation is not atomic after all (at least not on all cards)
That means it's possible to loose some interrupts because they came after the
copy step and hw cleared them on the clean step !
That's probably the reason we got missed beacons, got stuck queues etc and
couldn't figure out what was going on.
With this patch we switch from RaC operation to an alternative method (that
makes more sense IMHO anyway, I just chose to be on the safe side so far).
Instead of reading RAC registers, we read the normal PISR/SISR registers and
clear any bits we got by writing them back on the register. This will clear only
the bits we got on our read step and leave any new bits unaffected (at least
that's what docs say). So if any new interrupts come up we won't miss it.
I've tested this with an AR5213 and an AR2425 and it seems O.K.
Many thanks to Adrian Chadd for debuging this and reviewing the patch !
v2: Make sure we don't clear PISR bits that map to SISR generated interrupts

A new feature in the dongle firmware requires a handshake during
firmware intialization. The request is sent in event packets which the
host driver is not able to handle before any net device registered.
Discard those packets as the context for handling it is missing.
The initialization handler will be added as part of feature support
code in the future.

The check for alignment is not valid anymore and can be removed. The
function is collapsed with brcmf_sdioh_request_packet() as a consequence
because it did not add much functionality any longer.

The function is only called with sk_buff parameter being non-zero so
the prototype does not need to support passing a char buffer any longer.
When the function is called with a NULL sk_buff parameter it returns
-EINVAL now.

The conformance test limits (CTL) for each regulatory domains
(FCC/ETSI/MKK) are programmed for each runtime modes (11B,11G,
HT20 and HT40) in EEPROM. The lowest ctledge power value of a
particular running mode should not be used while computing
ctledge power for a different running mode.(i.e 11G's min ctledge
power should not be used while computing ctledge power for HT20).
Currently, the code does not handle this properly which would
result in incorrect txpowers in certain cases. So reset the
twiceMaxEdgePower to the default while computing min ctlegepower
for every mode.

When tx agg is being stopped TID is flushed using ath_tx_flush_tid. It
is possible that ath_tx_flush_tid completelly flushes TID (if all
packets in this TID have already been retried). If this happened
ath_tx_aggr_stop would leave TID in cleanup state permanently.
Fix this by making ath_tx_flush_tid remove AGGR_ADDBA_COMPLETE and
AGGR_CLEANUP flags from TID status if TID is empty.
