the netdump server have a zero checksum.

RFC 768 allows to not compute the checksum by leaving uh->check at 0 - hence it
is not illegal.
But without David's suggestion the code is not valid, since otherwise there is
no way of
distinguishing a computed `0' from an ignored `0' field:
if ( udph->check == 0 )
udph->check = -1;
