Subject: [dpdk-dev] [PATCH v6 3/3] net/iavf: implement new VLAN capability handling
Date: Tue, 12 Jan 2021 16:13:02 +0800
Message-ID: <20210112081302.87715-4-haiyue.wang@intel.com> (raw)
In-Reply-To: <20210112081302.87715-1-haiyue.wang@intel.com>

The new VLAN virtchnl opcodes introduce new capabilities like VLAN
filtering, stripping and insertion.

The AVF needs to query the VLAN capabilities based on current device
configuration firstly.

AVF is able to configure inner VLAN filter when port VLAN is enabled
base on negotiation; and AVF is able to configure outer VLAN (0x8100)
if port VLAN is disabled to be compatible with legacy mode.

When port VLAN is updated by DCF, the AVF needs to reset to query the
new VLAN capabilities.
