[1/3] ethdev: add flow api actions to modify IP addresses
Checks
Commit Message
Add actions:
- SET_IPV4_SRC - set a new IPv4 source address.
- SET_IPV4_DST - set a new IPv4 destination address.
- SET_IPV6_SRC - set a new IPv6 source address.
- SET_IPV6_DST - set a new IPv6 destination address.
Original work by Shagun Agrawal
Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>

Changes since RFC v2:
- Updated comments, help messages, and doc to indicate that IP/TCP/UDP
of the outermost headers are modified.
- Updated comments and doc to indicate that a corresponding valid flow
pattern item must be specified to offload corresponding header rewrite
action.
- Updated release notes.
