This timer (in seconds) provides debounce functionality for
an FDDI interface.
When the FDDI ring becomes non-operational, the LLC
interface will be disabled if the following conditions
hold TRUE:
1. fddimibMACMAUnitdataEnable (contained in
fddimibMACTable of rfc1512.mib) is enabled
2. This FDDI interface has been unavailable for
wfFddiXLineCfgLossOfServiceTmo seconds.
If the FDDI interface becomes enabled before
wfFddiXLineCfgLossOfServiceTmo expires, then the
timer is cancelled and nothing occurs.
This debounce timer may be disabled by setting it
to 0. In this case, when the FDDI interface becomes
non-operational, the LLC interface will be notified
right away.
