Fellow iSCSI MIB fans,

One more question for the list.  Another MIB review suggestion was to add more transport information:

  |  |  +--iscsiInstanceSsnErrorStatsTable(2)
  |  |     |
  |  |     +--iscsiInstanceSsnErrorStatsEntry(1) [iscsiInstIndex]
  |  |        |
  |  |        +-- r-n Counter32 iscsiInstSsnDigestErrors(1)
  |  |        +-- r-n Counter32 iscsiInstSsnCxnTimeoutErrors(2)
  |  |        +-- r-n Counter32 iscsiInstSsnFormatErrors(3)

Related states for transport are not provided in this table. Either a RowPointer
to another mib module is needed or a generic transport counter to indicate failure
at that layer was detected by iscsiInstance.

[Mark] This table was originally provided as just an error count table augmenting the whole iSCSI instance, and simply counts failures.  We (MIB authors) don't see a way for session-level details to fit into this purpose.  If anyone disagrees or sees a better way to do this, please speak up.
