This object specifies permitted methods of creating
entries in docsIfQosProfileTable.
CreateByManagement(0) is set if entries can be created
using SNMP. UpdateByManagement(1) is set if updating
entries using SNMP is permitted. CreateByModems(2)
is set if entries can be created based on information
in REG-REQ MAC messages received from Cable Modems.
Information in this object is only applicable if
docsIfQosProfileTable is implemented as read-create.
Otherwise, this object is implemented as read-only
and returns CreateByModems(2).
Either CreateByManagement(0) or CreateByModems(1)
must be set when writing to this object.
Note that BITS objects are encoded most significant bit
first. For example, if bit 2 is set, the value of this
object is the octet string '20'H.
