Support for raw ethernet packets queues

[xguerin]

Is your feature request related to a problem? Please describe. Not a problem. Support for raw ethernet packets, such as IBV_QPT_RAW_PACKET on verbs.

Describe the solution you'd like

• The ability to instantiate FI_RAWPACKET QP alongside existing FI* modes;
• The ability to register low-level flow steering on these QPs;

Describe alternatives you've considered Using Mellanox adapters with the verbs, or Solarflare adapters with ef_vi, or DPDK.

Additional context This is not exactly a feature request, just a question out of curiosity. I saw the raw ethernet packet support mentioned in one of the OFI charts, and I was wondering if there was a roadmap.

Raw endpoints are possible to define and add to the API. To date, there has not been sufficient interest in defining or implementing such a feature, mostly because applications interested in this typically use something like DPDK or XPD instead.
