Subject: [PATCH net-next 10/13] bridge: mrp: Implement netlink interface to configure MRP
Date: Mon, 20 Apr 2020 17:09:44 +0200 [thread overview]
Message-ID: <20200420150947.30974-11-horatiu.vultur@microchip.com> (raw)
In-Reply-To: <20200420150947.30974-1-horatiu.vultur@microchip.com>
Implement netlink interface to configure MRP. The implementation
will do sanity checks over the attributes and then eventually call the MRP
interface.
