Arpwatch ethercode dat updating

Arpsnmp has the same database features of arpwatch but relies on an external agent to collect the arp data.

This distribution contains a script, arpfetch, that uses snmpwalk from the CMU SNMP package.

This is a forked version of the original arpwatch licensed under the BSD license (afaik).

Since the 802.1Q tag inserts 32 bits between the MAC source address and the original Ethernet type field (0x806), the ARP data fields are not where arpwatch expects to see them.

I would patch this myself except that I'm not sure what the correct fix should be.
