``struct netconn *netconn_new_with_callback`(enum netconn_type type, u16_t proto, void (*callback) (struct netconn *conn, enum netconn_evt evt, u16_t len));`

## Description

This function is similar to `netconn_new_with_callback()` except that an additional parameter proto may be used to indicate the IP protocol number to use. If proto is non-zero, it must only be used with the type set to `NETCONN_RAW`.
