It can't.   Get over it!   Seriously, though, on an ethernet you don't
see this kind of corruption to an extent that matters, and on leased
lines, link-level diagnostics will turn up the problem before it bites
you on the ass.   It's only when you see error rates like this...

   sl0   296   <Link>                      49043  1389    68693     0  0
   sl0   296   204.182.18    49043  1389    68693     0  0

...that you see the occasional corrupt packet slip through the header
checksum.   Nonetheless, since a lot of us NetBSD hackers are in fact
on the other end of slip or ppp connections, a 32-bit CRC in sup would
be a big win.
