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

[Loftus, Ciara]

> Subject: [PATCH 1/7] net/iavf: disable broken QinQ strip on Rx
> 
> 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.
> 
> Fixes: 1e728b01120c ("net/iavf: rework Tx path")
