Created a way to clear the multicast forwarding cache on a socket without having to either remove the entries manually using the delete entry socket option or destroy and recreate the multicast socket.
Calling the socket option MRT_FLUSH will allow any combination of the four flag options to be cleared.
MRT_FLUSH_MFC will clear all non static mfc entries and clear the unresolved cache MRT_FLUSH_MFC_STATIC will clear all static mfc entries MRT_FLUSH_VIFS will clear all non static interfaces MRT_FLUSH_VIFS_STATIC will clear all static interfaces.
