According to the wiki, the correct way to initialize a DHCP interface is
to call dhcp_start() and not netif_set_up(). So, summarizing:
you can poll for netif.dhcp->state == DHCP_BOUND
you can define LWIP_NETIF_STATUS_CALLBACK, and call
void netif_set_status_callback(struct netif *netif,
netif_status_callback_fn status_callback);
your 'status_callback' function will be called when the interface comes
up after the DHCP state machine reached the DHCP_BOUND state and
netif_set_up() has been called by the dhcp code.
