Re: cvs commit: src/sys/dev/netif/nfe if_nfe.c if_nfereg.h
:I assume TCP works fine.
:Does it work on unfragmented UDP datagram?
:
:Best Regards,
:sephe
TCP seems to work, but it does MTU detection so it won't use
fragmented packets by default. ssh and TCP nfs mounts work.
UDP doesn't seem to work. I tried doing a 'ls -lda /usr/src' (my NFS
mount), using a UDP NFS mount, which should be a fairly small RPC,
and it locked up until I ifconfig'd -rxcsum -txcsum.
I tried configuring rxcsum and txcsum separately but either option
seems to blow up NFS.
I do not know whether the issue is packet fragmentation or DMA
fragmentation in the TX/RX rings.
