I have not really worked with the SNMP implementation that comes with
eCos. But yes, the value in snmpTrapOID is also an OID of the trap being
sent.

The second variable is snmpTrapOID.0, which contains
the administratively assigned name of the notification.
What does snmpTrapOID->OID should contain? I mean, snmpTrapOID
contains OID, which contains something else.
Should snmpTrapOID point to some variable OID, which is reason of
generating the trap?
