Subject: [PATCH net-next v2 4/6] net: dsa: qca: ar9331: add ageing time support
Date: Fri,  2 Jul 2021 12:17:49 +0200	[thread overview]
Message-ID: <20210702101751.13168-5-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210702101751.13168-1-o.rempel@pengutronix.de>

This switch provides global ageing time configuration, so let DSA use
it.
