This feature adds support for separate unicast and multicast counters, per ingress interface and per traffic class. 

This feature optimizes the utilization of hardware resources by sharing the hardware resources between different VLAN interfaces when they have the same ACL attached in the ingress direction. This is particularly useful for larger deployments where the ACL is applied to multiple VLANs and with the RACL sharing capability, lesser hardware resources are used irrespective of the number of VLANs
