[AGENT++] Size limit of an OctetString inside a MibTable ?

there is no size limit for the string itself, but if it is too long, you
cannot retrieve it any more ;-)

This indicates that the agent supports a bigger PDU size than the manager.

The default for snmp++/agent++ is
	#define MAX_SNMP_PACKET 4096
So 3KB will work, but 9KB not.

Note that the maximum message size is limited by UDP to 64K.
