- * Multicast sockets are slightly different from the other ones:
- * If you want to send packets only, just set the destination
- * address to the corresponding multicast group and iface to
- * the interface to be used. If you also want receiving, set
- * source address to the same multicast group as well.
+ * For SK_UDP or SK_IP sockets setting DA/DP allows to use sk_send(),
+ * otherwise sk_send_to() must be used.
+ *
+ * For SK_IP sockets setting DP specifies protocol number, which is used
+ * for both receiving and sending.
+ *
+ * For multicast on SK_UDP or SK_IP sockets set IF and TTL,
+ * call sk_setup_multicast() to enable multicast on that socket,
+ * and then use sk_join_group() and sk_leave_group() to manage
+ * a set of received multicast groups.
