From e6f1960ae6c736b7bb65a012809eb7c3654b42d7 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Mon, 25 Jun 2018 10:48:14 +0300 Subject: [PATCH] mlxsw: spectrum_router: Allocate FID according to PVID For bridge netdevices, instead of assuming that the router traffic is on VLAN 1, look at the bridge PVID. This patch assumes that the PVID doesn't change after the router interface is created (i.e. after the IP address is assigned).
