[PATCH 1/3] ath10k: fix calibration init sequence of qca99x0

[PATCH 1/3] ath10k: fix calibration init sequence of qca99x0

[Rajkumar Manoharan]

pre-calibration is meant for qca4019 which contains only caldata
whereas calibration file is used by ar9888 and qca99x0 that contains
both board data and caldata. So by definition both pre-cal-file and
cal-file can not coexist. Keeping them in shared memory (union), is
breaking boot sequence of qca99x0. Fix it by storing both binaries
in separate memories. This issue is reported in ipq8064 platform which
includes caldata in flash memory.

[PATCH 2/3] ath10k: remove unnecessary warning for probe response drops

[Rajkumar Manoharan]

qca99x0 and qca4019 solutions limit probe responses transmissions.
Logging warning message for each probe response drop is flooding
kernel log unnecessary with " failed to increase tx mgmt pending
count: -16, dropping". Hence reducing log level to debug.

[PATCH 3/3] ath10k: fix unconditional num_mpdus_ready subtraction

[Rajkumar Manoharan]

Decrement num_mpdus_ready only when rx amsdu is processed successfully.

Is there any realistic way to see this message if we are not running
many vAP on one radio?

I guess many probe requests or other management frames could also
cause this problem?

Should this patch be rebased on top of the "ath10k: process htt rx indication as batch mode" patch?

As of now this message can be seen only with qca99x0 which has 24 as 
max_probe_resp_desc_thres. Only possible way in single vAP is that in 
congested environment when DUT is receiving probe requests more 
frequently.

It should be on top of "ath10k: speedup htt rx descriptor processing for
