# This routine will look for NeXtWcale Fan Power Controllers (FPC) that have
# a default IP address of 192.169.0.100
#
# For each FPC found the code will
# 1 - ping the default IP address to get the default IP and MAC in the arp table
# 2 - use arp to get the MAC address
# 3 - lookup the MAC address
# ------ check for the MAC on the switch adn save the port number
# ------ lookup the node with that switch port number
# 4 - get the IP address for the node name found
# 5 - determine the assocaited netmask and gateway for this node IP
# 6 - use rspconfig (IPMI) to set the netmask, gateway, and IP address
# 7 - check to make sure that the new FPC IP address is responding
# 8 - remove the default FPC IP from the arp table
# 9 - use ping to determine if there is another default FPC IP and if so start this process again
