ZEP - ZigBee Encapsulation Protocol

A netif implementing the ZigBee Encapsulation Protocol (ZEP). This is used to tunnel 6LowPAN over UDP.

Usage (there must be a default netif before!):

netif_add(&zep_netif, NULL, NULL, NULL, NULL, zepif_init, tcpip_6lowpan_input);
netif_create_ip6_linklocal_address(&zep_netif, 1);
netif_set_up(&zep_netif);
netif_set_link_up(&zep_netif);
