From 26267bf9bb57d504c785d8659adc8e02b6629c95 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 24 Mar 2021 02:30:48 +0100 Subject: netfilter: flowtable: bridge vlan hardware offload and switchdev The switch might have already added the VLAN tag through PVID hardware offload. Keep this extra VLAN in the flowtable but skip it on egress. Signed-off-by: Felix Fietkau Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S.
