The value of tmnxMobGwRowStatus specifies the row status of this
entry. It is used for the creation and deletion of this mobile gateway.
In order for the row creation to succeed, value for tmnxMobGwType must
be included in the same SNMP SET PDU as tmnxMobGwRowStatus. Otherwise,
the SET request will fail with an 'inconsistentValue' error.
The creation or deletion of an entry in this table causes creation or
deletion of a corresponding entry in tmnxMobServTable or
tmnxMobPdnTable depending on the value of tmnxMobGwType.
To delete an entry from this table, the corresponding mobile gateway
must be administratively down.
