If routers check the IPv4 header checksum (which I think they are
supposed to for IPv4), then I don't think you will see packets with
IP checksum errors unless you are adjecent to a router/host that
is generating bad checksums. For example, on one router I have
access to that is exposed to a networks worth of random hardware,
I've seen 2 bac IP checksums from 333128929 IP packets. On another
home router I see 4 from 16089085.
However, in IPv6, these errors will be forwarded on and show up as
UDP or TCP checksum errors on end hosts.
