Subject: [patch net-next 13/14] mlxsw: spectrum: Enable FDB records for VLAN devices on top of LAG

From: Ido Schimmel <idosch@...lanox.com>

When adding or removing FDB records of VLAN devices on top of LAG we
should set the lag_vid parameter to the VLAN ID of the VLAN device. It
is reserved otherwise.
