Eric Garver df560056d9 udp: inuse checks can quit early for reuseport ... UDP lib inuse checks will walk the entire hash bucket to check if the portaddr is in use. In the case of reuseport we can stop searching when we find a matching reuseport. On a 16-core VM a test program that spawns 16 threads that each bind to 1024 sockets (one per 10ms) takes 1m45s. With this change it takes 11s. Also add a cond_resched() when the port is not specified. Signed-off-by: Eric Garver <e@erig.me> Signed-off-by: David S.
