cnat: Support offloaded check sums
This patch removes zero checks for new_addr, new_port
meaning sessions with zero values will rewrite the packet
with a 0 value instead of leaving it in place. This allows
to reduce branchiness in the code, and sessions are fully
resolved at creation time anyway.
This also adds support for checksum offloads:
- IP checksum offload : we always compute the checksum to
avoid issues with drivers. We'll revert this if we realize
cost gets too important.
- TCP/UDP checksum offload : we add the implementation for
pseudo header checksum computation. This is needed for the
drivers that do not re-compute this pseudo-checksum before
the packet is TX-ed (e.g. a few DPDK drivers).
Type: improvement
