[PATCH 1/7] net/iavf: disable broken QinQ strip on Rx

[Bruce Richardson]

When 2 VLANs are stripped from a packet, the iavf driver vector path
fails to handle them properly as it 'or's the two values together on the
assumption that only one is valid. Explicitly list the VLAN related
features supported by the vector path, rather than using the
"OFFLOAD_VLAN" group, thereby disabling advertising of QinQ stripping so
that a scalar path is used.
