8cfa7ef812 ath11k: move some tx_status parsing to debugfs code
Some of the fields are only used by debugfs. Move the parsing of these
from the data hot path to the debugfs code.

39e81c6a29 ath11k: fix missed bw conversion in tx completion
TX rate stats for the retried packets for a station comes through
tx completion events. Assigning hw reported bandwidth information
directly to station's txrate bandwidth will cause below warning.
Fix this warning by converting the hw reported bandwidth to
mac80211 base bandwidth.

d5c65159f2 ath11k: driver for Qualcomm IEEE 802.11ax devices
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first
supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k
uses mac80211 and supports AP, Station and Mesh modes.

Even though ath11k has some similar code as with ath10k (especially
the WMI layer) it was concluded to be simpler to have a "clean start"
for ath11k code base and not try to share the code with ath10k. This
makes maintenance easier and avoids major changes in ath10k, which
would have significantly increased the risk of regressions in existing
setups.

Even though the driver is very similar with ath10k but there are major
differences as well. The datapath is completely different. ath11k
supports multiple MACs, called "soc" in the firmware interface. And
there's only one WMI interface to support.

Currently ath11k supports only IEEE 802.11ac mode, but patches for
802.11ax are available and they will be submitted after ath11k is
accepted to upstream.

The firmware images are available from ath11k-firmware repository but
they will be also submitted to linux-firmware:

https://github.com/kvalo/ath11k-firmware

This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.

The driver has had multiple authors who are listed in alphabetical
order below.
