From 295b34f55b001bceb27d9177b55326ccda49351b Mon Sep 17 00:00:00 2001 From: Haiyue Wang Date: Thu, 4 Feb 2021 20:50:29 +0800 Subject: [PATCH] net/ice: fix VLAN 0 adding based on VLAN mode In Single VLAN Mode, single VLAN filters via ICE_SW_LKUP_VLAN are based on the inner VLAN ID, so the VLAN TPID (i.e. 0x8100 or 0x888a8) doesn't matter. In Double VLAN Mode, outer/single VLAN filters via ICE_SW_LKUP_VLAN are based on the outer/single VLAN ID + VLAN TPID. For both modes, adding a VLAN 0 + no VLAN TPID filter to handle untagged traffic when VLAN pruning is enabled. Also, this handles VLAN 0 priority tagged traffic in Single VLAN Mode, since the VLAN TPID is not part of filtering. If Double VLAN Mode is enabled then an explicit VLAN 0 + VLAN TPID filter needs to be added to allow VLAN 0 priority tagged traffic in DVM, since the VLAN TPID is part of filtering.
