Subject[PATCH net-next v4] ipmr: ip6mr: Create new sockopt to clear mfc cache or vifs
Date
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
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.
