This read-create RowStatus value controls the creation, activation, and deletion of an extended flow template's entry in the hpnicfFTExtendGroupTable, indexed by both the group index and the offset type. Admins set it to active once the offset and length match values are configured, activating that portion of the extended template. For example, an admin defining an extended template that matches at both the l2 and l4 offset types would set this RowStatus to active(1) for each of those two entries.
