Subject: [patch net-next 13/16] mlxsw: reg: Add Switch Virtual-Port Enabling register definition

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

In order for a port to support {Port, VID} to FID mapping it needs to be
configured to a virtual port mode (as opposed to VLAN mode).

Add the SVPE register, which enables port virtualization.
