A problem exists in the Fibre Channel v1.0 Core in which some of the receive error statistics are occasionally incorrect. When they are incorrect, the statistic counters might either miss the error and not count it or might count it twice. The two receive error statistics that this affects are:
- Rx10bErrCnt (0x08C) - Receive Decode Error Count
- RxOsdErrCnt (0x094) - Receive Ordered Set Disparity Error
A patch exists to fix this issue so that the Fibre Channel v1.0 Core receive error statistics function properly.
To resolve this issue, please install the patch that is available in the LogiCORE Fibre Channel v1.0 Core Release Notes and Known Issues Answer Record (Xilinx Answer 19527).
