Subject: [PATCH 3/3] ath11k: apply mgmt rate for beacons
Date: Fri,  5 Jul 2019 12:31:08 +0200	[thread overview]
Message-ID: <20190705103109.3731-4-sven@narfation.org> (raw)
In-Reply-To: <20190705103109.3731-1-sven@narfation.org>

From: Sven Eckelmann <seckelmann@datto.com>

ath11k is using the lowest basic rate to send management frames. But the
firmware is still sending the beacons at 1 Mbit/s for 2.4GHz and 6 Mbit/s
on 5GHz. But it could be that these rates are not part of the basic rates.
And thus the AP should not try to submit using these rates when clients
don't need to support these rates (and thus might not be able to receive
these rates).
