Subject: [PATCH] mac80211: fix invalid nss config
|
|
|
|
In HE-enabled STAs, HE-MCS Rx map filled with value 3 for all eight spacial
|
|
streams if tx/rxantenna configured as invalid value. Because of this, peer_nss
|
|
computed as 0 caused q6 crash during WMI_PEER_ASSOC_CMDID.
|
|
With this patch, HE STA supports at least single spactial stream HE-MCSs 0 to 7
|
|
(transmit and receive) in all supported channel widths and fixing the q6 crash.
