The RFC introduces Stateful Flow Table (SFT) API and changes needed in
both ethdev an RTE flow to support SFT functionality.

SFT library provides a framework for applications that need to maintain
context across different packets of the connection.

The goals of the SFT library:
- Accelerate flow recognition & its context retrieval for further
  lookaside processing.
- Enable context-aware flow handling offload.

Andrey Vesnovaty (3):
  ethdev: add item/action for SFT
  ethdev: support SFT APIs
  sft: introduce API
