Flow Scalability per Broadcom Chipset

The maximum entries of OpenFlow Flows is often a critical piece of any SDN solution. This is a summary of Openflow Flow scalability per family of Chipset.

Chipset	ICAP (maximum entries in default or match modes)					ECAP (entries)	VCAP (entries)	L2 (maximum entries when buffer-mode is 5)	L3 (maximum entries when buffer-mode 5)
Chipset	default	IPv4	IPv6	MAC	ARP	ECAP (entries)	VCAP (entries)	L2 (maximum entries when buffer-mode is 5)	IPv4 host route	IPv4 forwarding route	IPv6 host route	IPv6 forwarding route
