Improve port-sharing performance by allowing any process to receive packets from the shared hardware port under a spin lock for mutual exclusion. Previously, one process was nominated as the master and that process was responsible for receiving all packets from the shared hardware port and either consuming them or forwarding them to their destination. This led to starvation problems for other processes when the master process was busy in computation phases.
