[PATCH v2 1/4] net/i40e: fix supported offloads for Rx vector path

[Ciara Loftus]

The set of supported Rx offloads in the vector path had been defined as
those supported by the scalar path. This was incorrect so define a new
list of supported offloads for the vector path. The list is the same
as the scalar path except it excludes vlan extend and qinq strip.

Also, remove a redundant check for the VLAN Extend offload in the
driver code. This check is now performed in the common rx path
selection code.

Fixes: 052ae311091c ("net/i40e: use the common Rx path selection infrastructure")
