Subject: [PATCH v4 net-next 04/15] mlxsw: spectrum: refactor leaving an 8021q upper that is a bridge port
Date: Mon, 19 Jul 2021 00:44:23 +0300	[thread overview]
Message-ID: <20210718214434.3938850-5-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20210718214434.3938850-1-vladimir.oltean@nxp.com>

For symmetry with mlxsw_sp_port_lag_leave(), introduce a small function
called mlxsw_sp_port_vlan_leave() which checks whether the 8021q upper
we're leaving is a bridge port, and if it is, stop offloading that
bridge too.
