DESCRIPTION
This file contains the initialization routine for the INCLUDE_DHCPC component.
When DHCP is used to get the target's address and boot file, this routine
executes between the startup routines (in the usrNetDhcpcBootSetup.c module)
for the INCLUDE_DHCPC_LEASE_GET and INCLUDE_DHCPC_LEASE_TEST components.
