David Held 2dc41cff75 udp: Use hash2 for long hash1 chains in __udp*_lib_mcast_deliver. ... Many multicast sources can have the same port which can result in a very large list when hashing by port only. Hash by address and port instead if this is the case. This makes multicast more similar to unicast. On a 24-core machine receiving from 500 multicast sockets on the same port, before this patch 80% of system CPU was used up by spin locking and only ~25% of packets were successfully delivered. With this patch, all packets are delivered and kernel overhead is ~8% system CPU on spinlocks.
