Just as an evidence that the ``path MTU discovery'' seems to work.
I'm doing all my remote traffic via SLIP with an MTU of 552 (not even
576). Anyway:
j@uriah 1314% netstat -s | fgrep fragment
0 fragments received
0 fragments dropped (dup or out of space)
0 fragments dropped after timeout
0 output datagrams fragmented
0 fragments created
0 datagrams that can't be fragmented
