Well, I looked at it under wireshark and the readdir reply looks fine.
(It is made up of two IP fragments, but wireshark reassembles them ok
and says the checksums are ok. The contents look like a valid Readdir
RPC reply.) Maybe NetBSD doesn't reassemble the IP fragments correctly
or has an issue w.r.t. the checksum, but Wireshark thinks it's aok.
ps: I vaguely recall that the problem went away when you used TCP
instead. Is that correct?
