ICMP Echo and Echo reply packets mangled the ICMP checksum when no mangling was needed.
Other ICMP message types may still be wrong since they potentially contain IP header information that may or may not need IP addresses manipulated
Increased the ARP table size from 8 to 64 since the ARP RFC (826) suggests that ARP info from all received ARP packets be gathered as ARP broadcasts are received. A normal LAN can easily blow over an 8 entry ARP table.

Looks good. I like the debug logging methods. Will make it easier to debug problems in future. Will pull this in tonight.
