From 7cbecf245ade1739f34e00a10b2cdedd851bd7f4 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 26 May 2017 08:37:28 +0200 Subject: [PATCH] mlxsw: spectrum_router: Replace vPorts with Port-VLAN We're going to get rid of vPorts completely later in the patchset, but the router code is self-contained, so it's a good candidate to start the transition with. Convert all the functions that expects to operate on a vPort to operate on a Port-VLAN instead. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
