PLB Address Map and Register Definitions

The entire address space is now described in two sections:

•“Ethernet AVB Endpoint Address Space”

•“Tri-Mode Ethernet MAC Address Space” (which can be addressed through the Ethernet AVB Endpoint core Address Space). This address is only present when the core is generated in “Standard CORE Generator Format”.
