so you mean:

netif_set_default(netif_add(&netif, &ipaddr, &netmask, &gw, NULL,pcapif_init, tcpip_input));
  dhcp_set_struct(&netif, &netif_dhcp);
  dhcp_start(&netif);

is enough?
You can even leave away dhcp_set_struct(): it's only a helper to prevent dhcp_start() calling mem_malloc() to allocate its struct. If you make sure the tcpip_thread is started after these calls (or you do these calls from the 'initialized' callback), it should run fine.
