MU-MIMO Rx involves different interpretation of the VHT-SIG-A compared to SU-MIMO. The incorrect interpretation led ath10k to report VHT MCS values greater than 9 which subsequently prompted mac80211 to drop such frames. This effectively broke Rx with MU-MIMO in many cases and manifested with a kernel warning in the log which looked like this: [ 14.552520] WARNING: CPU: 2 PID: 0 at net/mac80211/rx.c:3578 ieee80211_rx+0x26c/0x940 [mac80211]() [ 14.552522] Rate marked as a VHT rate but data is invalid: MCS: 10, NSS: 2 ... call trace follows ...
