Subject: [dpdk-dev] [PATCH v1] net/iavf: fix unsupported VLAN offload requested
Date: Mon, 25 Jan 2021 12:30:54 +0800	[thread overview]
Message-ID: <20210125043054.4998-1-haiyue.wang@intel.com> (raw)

If the underlying PF doesn't support a specific ethertype or the ability
to toggle VLAN insertion and/or stripping, then the VF prevents sending
an invalid message to the PF.

Fixes: 1c301e8c3cff ("net/iavf: support new VLAN capabilities")
