This field can take the following values:
CBI_M2_UPDATE_TEST This value instructs L2 to check that the specified
parameters are acceptable (but not to apply
them). If the parameters are not acceptable, then
the request is rejected. If the parameters are
acceptable, then L2 must accept a subsequent
CBI_M2_UPDATE_PARMS with an update_type
update_type update_type
update_type set
to CBI_M2_UPDATE_SET carrying the same
