Specifies the Mac Frame Error Threshold for determining when
a MAC Frame Error Condition report will be generated (via an SRF
Frame). If Mac Frame Error Ratio is greater than Mac Frame Error
Threshold then the Mac Frame Error Condition exists. This Mac Frame
Error Ratio is calculated periodically based on the attributes
wfFddiMacErrorCts and wfFddiMacLostCts. A low value of Mac Frame
Error Threshold will generate more frequent Mac Frame Error
conditions if the wfFddiMacErrorCts and wfFddiMacLostCts counters
are periodically increased. Therefore the user should set the Mac
Frame Error Threshold (1..65535) in accordance with the volatility
of the ring.
