Urgency: Standard

General Description:
This Answer Record describes improvements made in the OPB 10/100 Ethernet MAC in EDK 6.1i Service Pack 2.

解决方案

As of EDK 6.1i SP2, the VxWorks adapter now supports the sending and receiving of multicast packets. (Please note that hardware and software do not support filtering on multicast addresses.)

The following issues have been fixed in the EDK 6.1i SP2 release of v1.00.m of the OPB 10/100 Ethernet MAC core:

- The core did not respond correctly to a packet with a bad or missing End Of Stream character.
- In certain circumstances, the core did not respond correctly to a late collision occurring at the very end of a packet.

The following enhancement have also been made:

- A more precise collision response.
- A parameterizable MII interface clock frequency generation.
- Support of multicast receive without using promiscuous address mode.

These fixes are provided in the latest 6.1i EDK Service Pack, available at:
http://www.xilinx.com/ise/embedded/edk.htm.
The first service pack containing the fix is EDK 6.1i Service Pack 2.
