A new version of the OPB Ethernet Lite MAC (v1.02a) is introduced in EDK 6.3.02i to reflect the following changes. The new version is opb_ethernetlite_v1_02_a. The following bug fixes and enhancements are in the EDK 6.3.02i release of the OPB Ethernet Lite MAC v1.02a Core: 

 

- Added support for jumbo size frames and CAM-based receive address validation. This functionality can be included or excluded at build time. The CAM may be implemented in BRAM or logic. This did not affect the signal interface, but it did change the parameter interface. 

 

- Modified the parameters to allow for different receive and transmit packet FIFO sizes. Also added a parameter to allow MAC FIFOs be implemented in Block RAM or logic. This did not change the signal interface, but it did change the parameter interface. 

 

- Changed parameter C_HALF_DUPLEX_EXIST so it can now me changed and builds can be performed without the half duplex circuitry as desired.
