Subject: [PATCH v3] ath11k: Fix downlink MU-MIMO
Date: Tue, 30 Apr 2019 19:41:56 -0700 [thread overview]
Message-ID: <1556678516-12844-1-git-send-email-milehu@codeaurora.org> (raw)
In vdev start command, prefer tx and rx streams are mandatory to enable DL MU-MIMO.
Tested only on 11ac mode.
Signed-off-by: Miles Hu <milehu@codeaurora.org>

V2:
- remove 11ac mode from the subject.
V3:
- clarify the fix for downlink mu-mimo and mention the consequence of not set the
value in the comment.
