Subject: [PATCH net-next v3 1/2] net: stmmac: don't clear network statistics in .ndo_open()
Date: Tue, 20 Jun 2023 00:52:19 +0800	[thread overview]
Message-ID: <20230619165220.2501-2-jszhang@kernel.org> (raw)
In-Reply-To: <20230619165220.2501-1-jszhang@kernel.org>

FWICT, the common style in other network drivers: the network
statistics are not cleared since initialization, follow the common
style for stmmac.
