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. drivers/net/wireless/ath/ath11k/mac.c | 3 +++ 1 file changed, 3 insertions(+)
