Summary:  ifconfig command does not flush ARP cache

Original Submission:  The ifconfig function does not flush the entries in the 
ARP cache when it changes the server's or the gateway's IP address.

The sequence
 module (nd)/foo
 module (nd)/bar

will result in the TFTP request for /bar being sent to at's MAC 

The patch below fixes this problem by invalidating (zeroing) the respective ARP 
cache entry when changing the gateway or server IP. An ARP request will be 
issued on next use of the IP, installing the correct MAC address.
