Well now that's odd. I tried:
time ping -l10000 -c1 -s100 -q mnm
to send 10,000 100 byte packets. They were all received, according to
'ifconfig eth0'. The command took 4.47 seconds wallclock time.
That's a miserable 1.8 mbits/sec. The sender is an ISA ne2k on 10bT.
I would expect that there would be a lot of queue pressure on the
sending side under these circumstances. The sender is kernel 2.2.13.
