From e96a6e027510279a5089b24e2f217693488327f3 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 30 Mar 2017 17:37:13 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: remap existing bridge members When a local port of a switch chip becomes a member of a bridge group, we need to reprogram the Cross-chip Port Based VLAN Table (PVT) to allow existing cross-chip bridge members to egress frames on the new ports. There is no functional changes yet, since the PVT is still programmed with all ones, allowing any external port to egress frames locally.
