OK, everything is working fine.  You just have some sort of routing
misconfiguration.
Do 'route -n' or check /proc/net/route.
Do 'arp -n' or check /proc/net/arp.

Ignore the count put out by 'ping' -- until you get a valid ARP response you
are not really sending out packets.

You are receiving packets -- 'tcpdump' will likely show they are broadcast
ARPs from other machines.

One for each transmitted and recieved packet....

Yup.  The option name is, confusingly, "options".
