Subject: [PATCH 02/12] wifi: mt76: mt7915: allow processing TXS for 'NO_SKB' pkt-ids
Date: Wed, 27 Jul 2022 16:01:12 -0700	[thread overview]
Message-ID: <20220727230122.29842-2-greearb@candelatech.com> (raw)
In-Reply-To: <20220727230122.29842-1-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

This will let us update stats and wcid.rate for every TXS
callback we receive for a particular wcid.

For now, the TXS is not requested for NO_SKB frames, however.
That will be allowed in next patch.
