> VXLAN-GPE extends VXLAN protocol and provides the next protocol field
> specifying the first inner header type.
> 
> The application can assign some explicit value to VXLAN-GPE::next_protocol
> field or set it to the default one. In the latter case, the rdma-core library
> cannot recognize the matcher built by PMD correctly, and it results in
> hardware configuration missing inner headers match.
> 
> The patch forces VXLAN-GPE::next_protocol assignment if the application did
> not explicitly assign it to the non-default value
