This series of patches add support for 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.
- SET_TP_SRC - set a new TCP/UDP source port number.
- 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.

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

v2
- Remove OpenFlow prefix.
- Remove Network (NW) prefix from IPv4 and IPv6 rewrite actions.
- Re-based to tip.
