Subject: mlxsw: spectrum: Handle PORT_PRE_BRIDGE_FLAGS
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c19c44f867ca3c0bb3b820c9234590dbd0f7afbe;p=openwrt%2Fstaging%2Fblogic.git

mlxsw: spectrum: Handle PORT_PRE_BRIDGE_FLAGS

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.
