I think that there should be a standard macro defined in <netinet/ip.h>
that says whether or not this change is in the kernel, so that people
don't have to send themselves a packet to see whether the kernel byte
swaps or not.

Do you have any desire to do anything about raw_input as well?  Various
fields are messed with on the way in, too.
