Subject: [PATCH] ath11k: mask out vht beamforming if a fixed rate is set
Date: Tue, 17 Dec 2019 18:18:27 +0100	[thread overview]
Message-ID: <20191217171827.6780-1-john@phrozen.org> (raw)

From: Ritesh Singh <ritesi@codeaurora.org>

After setting a fixed vht-rate we see a FW assert if a STA tries to
(re)assoc with the mu_bfee cap set. This patch masks out the capability
bits if a fixed rate is set.
