recv-multicast-scaling Parameter

Description

Defines system-wide default value to enable receiving multicast packets through a more scalable data path that uses extra worker threads to deliver multicast packets. Multicast applications are usually streaming data type, where packets are small but the packet rate can be very high. The normal data path cannot handle very high packet rate without drops. This problem is especially acute when there are multiple receivers for the same multicast group. However, for the general case, there might be a tradeoff between latency and scalability.
