+2.3.27 Set Mode Payload
+
+Set Mode Payload is used by servers and routers to distribute to each
+other the information about changed modes in the SILC network. The
+payload is sent when channel's or client's channel mode is changed.
+Server can send this to router which will broadcast it further to other
+routers. However, normal server must not reiceve this payload. Client
+must not send or receive this payload.
+
+The payload may only be sent with SILC_PACKET_SET_MODE packet.
+It must not be sent in any other packet type. Following diagram
+represents the Set Mode Payload.
