When I ping from the other machine I get similar results (nobody is home and
the count of RX packets in ifconfig doesn't change.)
The outgoing packet does make it to the other machine - if I run a packet
sniffer there I can see the ping come in (based on the ARP request mac
src/dest)

lsmod gives the following line for the ethernet :

No it is a single port.
