From 56f0569e3ab741d3c5cebc4b4c882b471df53738 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Mon, 15 Jun 2015 15:00:53 -0700 Subject: [PATCH] fm10k: only prevent removal of default VID rules This allows us to correctly add a VLAN even if it matches our default VID. However, we don't want to remove the VID rules once that VLAN is deleted. Correctly remove the stack layers information of the VLAN, but then return to forwarding that VID as untagged frames. If we deleted the VID rules here, we would begin dropping traffic due to VLAN membership violations.
