Add virtchnl protocol header and field definitions for advanced RSS
configuration including GTPC, GTPU, L2TPv2, ECPRI, PPP, GRE, and IP
fragment headers.
- Define new virtchnl protocol header types
- Add RSS field selectors for tunnel protocols
- Extend static mapping arrays for protocol field matching
- Add L2TPv2 session ID and length+session ID field support
This provides the foundational definitions needed for VF RSS
configuration of tunnel protocols.
