From 1f65da742d15462786533cf3ea58335aa32e3daa Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 16 Oct 2015 14:01:34 +0200 Subject: [PATCH] mlxsw: reg: Add Switch Virtual-Port Enabling register definition 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. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
