If you're going to add an IP option, you can eliminate the
problem entirely. Just add an "extended IP ID" IP option and give
it as many bits as you want-- make that the high order of an n+16-bit
IP ID.
The IP timestamp option, if done per frag and required to be
the same for all frags, could be used in this way, since you
presumably won't wrap without incrementing that by at least 1. :-)
