[PATCH 0/2] Fix tx stats inconsistencies

[Rakesh Pillai]

The rate table indexes and the NSS values are
incorrect, causing the tx stats to be displayed
incorrectly.

This patchset fix these issues in the tx stats

[PATCH 1/2] ath10k: Fix rate table updation in tx stats

[Rakesh Pillai]

The index for updating rate table, which is displayed
in the tx stats via debugfs, is calculated using the
bandwidth value. The bandwidth values do not map
correctly with the bandwidth values shown in the rate table.

Correct the bandwidth value calculation which is used
to calculate the index for rate table updation for tx stats.

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1

Fixes: e88975ca37d1 ("ath10k: dump tx stats in rate table format")

[PATCH 2/2] ath10k: Fix NSS tx stats for legacy rates

[Rakesh Pillai]

The ratecode field given by firmware in the tx stats
gives the details of NSS and MCS, if the preamble
specifies that it is HT/VHT. In case of OFDM/CCK, as
specified by the preamble, the ratecode indicates the
legacy rate instead of NSS/MCS data. For OFDM/CCK cases,
the NSS should always be 1, i.e. 1x1 mode for 11g and 11b.

Currently the legacy rate is misinterpreted as NSS & MCS, leading
to incorrect updation of tx stats corresponding to NSS, which is
displayed in the tx stats via debugfs.

Fix the nss value to 1 for 11b and 11g modes by checking
the preamble indication in the ratecode provided by the firmware.
