[dpdk-dev] [RFC 0/3] ethdev: add IP address and TCP/UDP port rewrite actions to flow API

[Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>]

This series of patches add support for actions:
- OF_SET_NW_IPV4_SRC - set a new IPv4 source address.
- OF_SET_NW_IPV4_DST - set a new IPv4 destination address.
- OF_SET_NW_IPV6_SRC - set a new IPv6 source address.
- OF_SET_NW_IPV6_DST - set a new IPv6 destination address.
- OF_SET_TP_SRC - set a new TCP/UDP source port number.
- OF_SET_TP_DST - set a new TCP/UDP destination port number.

These actions are useful in Network Address Translation use case
to edit IP address and TCP/UDP port numbers before switching
the packets out to the destination device port.

The IP address and TCP/UDP port rewrite actions are based on
OFPAT_SET_NW_SRC, OFPAT_SET_NW_DST, OFPAT_SET_TP_SRC, and
OFPAT_SET_TP_DST actions from OpenFlow Specification [1].

Patch 1 adds support for IP address rewrite to rte_flow and testpmd.

Patch 2 adds support for TCP/UDP port rewrite to rte_flow and testpmd.

Patch 3 shows CXGBE PMD example to offload these actions to hardware.

Feedback and suggestions will be much appreciated.

Thanks,
Rahul
