Subject: [PATCH] rtw88: fix rate mask for 1SS chip
commit 35a68fa5f96a80797e11b6952a47c5a84939a7bf upstream.
The rate mask is used to tell firmware the supported rate depends on
negotiation. We loop 2 times for all VHT/HT 2SS rate mask first, and then
only keep the part according to chip's NSS.
This commit fixes the logic error of '&' operations for VHT/HT rate, and
we should run this logic before adding legacy rate.
To access HT MCS map, index 0/1 represent MCS 0-7/8-15 respectively. Use
NL80211_BAND_xxx is incorrect, so fix it as well.
