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
tftpserver 1.1.1.1
module (nd)/foo
tftpserver 2.2.2.2
module (nd)/bar
will result in the TFTP request for /bar being sent to 2.2.2.2 at 1.1.1.1's MAC
address.
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.
