Subject: mt76: mt7603: increase dma mcu rx ring size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e970e6659899158871bae82e7c5aaf7eeabacb72;p=linux.git

mt76: mt7603: increase dma mcu rx ring size

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
