Subject: [RFC PATCH v3 net-next 10/24] net: prestera: guard against multiple switchdev obj replays on same bridge port
Date: Mon, 12 Jul 2021 18:21:28 +0300	[thread overview]
Message-ID: <20210712152142.800651-11-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20210712152142.800651-1-vladimir.oltean@nxp.com>

Prepare the prestera driver, which supports LAG offload, to deal with
bridge switchdev objects being replayed on the LAG bridge port multiple
times, once for each time a physical port beneath the LAG calls
switchdev_bridge_port_offload().
