Subject: [PATCH net-next 3/9] mlxsw: spectrum: Check bridge flags during prepare phase
Date: Wed, 13 Feb 2019 14:06:32 -0800	[thread overview]
Message-ID: <20190213220638.1552-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20190213220638.1552-1-f.fainelli@gmail.com>

In preparation for getting rid of switchdev_port_attr_get(), have mlxsw
check for the bridge flags being set through switchdev_port_attr_set()
when the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier is
used.
