Subject: [PATCH net-next v3 4/6] net: dsa: qca: ar9331: add ageing time support
Date: Mon, 2 Aug 2021 15:10:35 +0200 [thread overview]
Message-ID: <20210802131037.32326-5-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210802131037.32326-1-o.rempel@pengutronix.de>
This switch provides global ageing time configuration, so let DSA use
it.
