code in nx_dhcp_received_data_process in the nxd_dhcp_client.c to switch
packets that should be stamped for the secondary interface. Note to that DHCP Client
is modified in nx_dhcp_start() to set the XID arbitrarily. This simply facilitates
using the server responses (using "C arrays" from a real packet trace).*/
