that points at the IP header if it exists.

552a24e07c Add an option to ignore packets sourced from particular subnets.
It's implemented with a new set[subnet] option named ignore_checksums_nets.

If you populate this set with subnets, any packet with a src address within
that set of subnets will not have it's checksum validated.
