From ebb1bb401303ffac0ee994ba8ed9dfd24bb2ac5f Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Tue, 16 Mar 2021 21:10:17 +0100 Subject: net: ocelot: Add PGID_BLACKHOLE Add a new PGID that is used not to forward frames anywhere. It is used by MRP to make sure that MRP Test frames will not reach CPU port. Signed-off-by: Horatiu Vultur Signed-off-by: David S.
