I just read a different thread about problems with checksums on vge (and nfe in
the replies).
I'll just chime in here with some more information - I have a couple other
message threads going about some weird high packet volumes on my new FreeBSD
8.0-Release NFS server. I thought it might be an issue with the igb driver so
I put in a new card using em instead and got the exact same behavior. I'm
currently sifting through a tcpdump in wireshark and there are all sorts of
messages in there about checksums being incorrect - both TCP and UDP. This is
for communications between this client machine (FreeBSD 7.0-Release) and any of
the 8.0 machines I have. The packets going to non-8.0 machines (at least so
far) appear to be fine.
I'll defer to those who know more than I about the networking code, but is
there perhaps an issue in general with the checksuming and not specific to one
card or driver - is that even possible? That's now 4 different drivers all
with various checksum problem reports.
I'm going to be working on this all day today (and likely over the weekend) so
if I can help by supplying information please let me know what you need.
