It all depends if the user application is using a single thread or multiple threads to drain the queue. Since we used to grab socket lock in udp_recvmsg(), I guess nobody uses multiple threads to read packets from a single socket. So heavy users must use SO_REUSEPORT already, not sure what we would gain trying to go to a single socket, with the complexity of mem charging. >
