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
