Subject: [PATCH 4/5] mt76: mt7603: increase dma mcu rx ring size
Date:   Mon, 27 Jan 2020 19:17:53 +0100
Message-Id: <20200127181754.2810-4-nbd@nbd.name>

Content-Transfer-Encoding: 8bit
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

The ring is used for looping back tx powersave filtered frames, so it could
use some more room, in case more than one aggregate was queued
