Subject: [PATCH net-next v4 12/12] net: bridge: Add port attribute IFLA_BRPORT_MRP_IN_OPEN
Date: Tue, 14 Jul 2020 09:34:58 +0200	[thread overview]
Message-ID: <20200714073458.1939574-13-horatiu.vultur@microchip.com> (raw)
In-Reply-To: <20200714073458.1939574-1-horatiu.vultur@microchip.com>

This patch adds a new port attribute, IFLA_BRPORT_MRP_IN_OPEN, which

MRP_InTest frames.
