The value of tmnxGreTunnelReassembly specifies the maximum number
of seconds to wait to receive all fragments of a particular IPSec
or GRE packet for reassembly.
The tmnxGreTunnelReassembly value set to zero indicates that
reassembly is disabled.
The tmnxGreTunnelReassembly value set default indicates that this
value will be derived from the value of
TIMETRA-CHASSIS-MIB::tmnxIPsecIsaGrpTunnelReassembly object.
An 'inconsistentValue' error is retuned if the value is not a multiple
of 100 milli-seconds.
