From bcfd780144371fa0156176fa5518d4dabcd5aab9 Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Mon, 1 Jun 2015 11:39:04 -0700 Subject: [PATCH] rocker: install untagged VLAN (vid=0) support for each port On port probe, install by default untagged VLAN support. This is equivalent to running the command: bridge vlan add vid 0 dev DEV self A user could, if they wanted, manaully removing untagged support from the port by running the command: bridge vlan del vid 0 dev DEV self But installing it by default on port initialization gives the normal expected behavior.
