Subject: [patch net-next 12/16] mlxsw: reg: Add Switch VID to FID Allocation register definition

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

An incoming packet can be classified into a filtering identifer (FID)
based on its VID or incoming port and VID ({Port, VID}).

Add the SVFA register, which controls this mapping.
