ath9k: try more than one tid when scheduling a new aggregate
Sometimes the first TID in the first AC's list is not available for forming
a new aggregate (the BAW might not allow it), however other TIDs may have
data available for sending.
Prevent a slowdown of other TIDs by going through multiple entries until
we've either hit the last one or enough AMPDUs are pending in the hardware
queue.

ath9k_htc: keep calibrated noise floor value for oper channel
The ath9k_hw assumes that caldata is valid only for
oper channel. But with ath9k_htc case, the caldata is
passed for all channels on hw_reset though we are not doing
calibration on that channel. So the oper channel's nf history
got cleared to default due to mismatch in channel flags.
This patch also saves some space.

ath9k_hw: partially revert "fix dma descriptor rx error bit parsing"
The rx error bit parsing was changed to consider PHY errors and various
decryption errors separately. While correct according to the documentation,
this is causing spurious decryption error reports in some situations.
Fix this by restoring the original order of the checks in those places,
where the errors are meant to be mutually exclusive.
If a CRC error is reported, then MIC failure and decryption errors
are irrelevant, and a PHY error is unlikely.

mac80211: add hw configuration for max ampdu buffer size
Some devices don't support the maximum AMDPU buffer size of 64, so we
need to add an option to configure this in the hardware configuration.
This value will be used in the ADDBA response instead of the value
suggested in the request, if the latter is greater than the max
supported.

ath9k: reduce the likelihood of baseband hang check false positives
Since baseband hangs are rare, but the hang check function has a high
false positive rate in some situations, we need to add more reliable
indicators.
In AP mode we can use blocked beacon transmissions as an indicator,
they should be rare enough.
In station mode, we can skip the hang check entirely, since a true
hang will trigger beacon loss detection, and mac80211 will rescan,
which leads to a hw reset that will bring the hardware back to life.
To make this more reliable, we need to skip fast channel changes
if the hardware appears to be stuck.

txtid->seq_start may not always be up to date, when there is HT non-AMPDU

it is clearly not.
