From 40c766d4a49cdfe30e0fb40825321b4d4de651aa Mon Sep 17 00:00:00 2001 From: Ritesh Singh Date: Fri, 10 Apr 2020 22:36:44 +0530 Subject: [PATCH] ath11k: Fix fw assert by setting proper vht cap After setting fixed vht-rate if new station is trying to assoc with mu_bfee cap, or if a sta is already connected with mu_bfee cap then set the fixed vht-rate and reconnecting the sta, FW assert is happening. So to avoid this, reset the MU_BEAMFORMEE bit in vht->caps, if mcs_index is invalid for nss 1.
