tmnxOamLTtraceHopInfoTable defines the Alcatel-Lucent SROS OAM LDP
Trace Hops table for keeping track of the results of an LDP Tree Trace
test on a per hop basis.
An entry is added to the tmnxOamLTtraceHopInfoTable when a
hop is discovered after setting the tmnxOamTrCtlAdminStatus
object of the tmnxOamTrCtlEntry (having tmnxOamTrCtlTestMode
as ldpTreeTrace) to 'enabled(1)'. An entry is removed from the
tmnxOamLTtraceHopInfoTable when its corresponding tmnxOamTrCtlEntry
is deleted.
