From b360d94f1b8647bc164e7519ec900471836be14a Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 12 Feb 2021 17:15:58 +0200 Subject: net: mscc: ocelot: use separate flooding PGID for broadcast In preparation of offloading the bridge port flags which have independent settings for unknown multicast and for broadcast, we should also start reserving one destination Port Group ID for the flooding of broadcast packets, to allow configuring it individually.
