A row in this table contains statistical information about an LDP
Interface or Targeted peer.
Some counters contained in a row are for fatal errors received
during a former LDP Session associated with this entry. For example,
an LDP Pdu received on a TCP connection during an LDP Session
contains a fatal error. That error is counted here, because the
session is terminated.
If the error is NOT fatal (i.e. and the Session remains), then the
error is counted in the vRtrLdpSessionStatsEntry.
