> Subject: [PATCH v5] net/iavf: support flex desc metadata extraction
> 
> Enable metadata extraction for flexible descriptors in AVF, that would
> allow network function directly get metadata without additional parsing
> which would reduce the CPU cost for VFs. The enabling metadata
> extractions involve the metadata of VLAN/IPv4/IPv6/IPv6-FLOW/TCP/MPLS
> flexible descriptors, and the VF could negotiate the capability of
> the flexible descriptor with PF and correspondingly configure the
> specific offload at receiving queues.
