[SNMP4J] set a tablerow

[Frank Fock]

Hi Stefan,

You can, of course, create a row in any SNMP table that supports row 
creation
by sending one or more SET PDUs with SNMP4J.

However, if there is no RowStatus column in that table then it totally 
depends on
the agent how the row can be created. How a row is then created should be
documented in the table's MIB specification.

This is not an issue we can solve.

Best regards,
Frank
