From 903fcf734f468afb5a3f153f870f58e4c1d5e525 Mon Sep 17 00:00:00 2001 From: Nir Dotan Date: Thu, 9 Aug 2018 11:59:07 +0300 Subject: [PATCH] mlxsw: spectrum_flower: Disallow usage of vlan_id key on egress As recent spectrum FW imposes a limitation on using vlan_id key for egress ACL, disallow the usage of that key accordingly and return a proper extack message.
