Subject: [dpdk-stable] [PATCH 20.11 v2 16/18] net/ice: fix VLAN 0 adding based on VLAN mode
Date: Fri, 11 Jun 2021 15:15:28 +0800
Message-ID: <20210611071531.48411-17-haiyue.wang@intel.com> (raw)
In-Reply-To: <20210611071531.48411-1-haiyue.wang@intel.com>

[ upstream commit 295b34f55b001bceb27d9177b55326ccda49351b ]

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.

Fixes: 14e7a4b37b4f ("net/ice/base: support configuring device in double VLAN mode")
