Hey,
I've one question:
Do those APIs support modify inner IP headers?
In our scenarios, we need to specific that NAT action is on inner or outer IP header.
Thanks,

> 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.
