Subject: [PATCH 11/12] wifi: mt76: mt7915: add ethtool tx/rx pkts/bytes
Date: Wed, 27 Jul 2022 16:01:21 -0700	[thread overview]
Message-ID: <20220727230122.29842-11-greearb@candelatech.com> (raw)
In-Reply-To: <20220727230122.29842-1-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

These stats are provided with same name by ath10k
and some intel wired NIC drivers.  Add them to mt7915
as well to allow user-space code to more easily get some
basic stats out of the radio.
