/* Testing the multiple interface DHCP Client */
/* This is the DHCP Client that will run on both interfaces independently.
Required: NX_MAX_PHYSICAL_INTERFACES >= 2 and NX_DHCP_CLIENT_MAX_RECORDS >= 2.
There are two DHCP Client threads that independently activate the DHCP Client on
the primary or secondary interface. When they reach the bound state, each interface Client
deactivates the DHCP Client process and the DHCP Client goes back to the NOT STARTED state.
There is one server thread handling DHCP Client messages on both interfaces.
