* A STREAMS driver or module can optionally select inner and outer perimeters.

* D_MTPERMOD - per module single threaded.
* D_MTQPAIR - per queue-pair single threaded.
* D_MTPERQ - per queue instance single threaded.
* (none of the above) - no inner perimeter restricting concurrency
*

* D_MTOUTPERIM - a per-module outer perimeter. Can be combined with
* D_MTPERQ, D_MTQPAIR, and D_MP.
*
* The concurrency when entering the different STREAMS entry points can be
* modified with:
* D_MTPUTSHARED - modifier for D_MTPERQ, D_MTQPAIR, and D_MTPERMOD
* specifying that the put procedures should not be
* single-threaded at the inner perimeter.
* _D_MTOCSHARED - EXPERIMENTAL - will be removed in a future release.
* Modifier for D_MTPERQ, D_MTQPAIR, and D_MTPERMOD
* specifying that the open and close procedures should not be
* single-threaded at the inner perimeter.
* _D_MTCBSHARED - EXPERIMENTAL - will be removed in a future release.
* Modifier for D_MTPERQ, D_MTQPAIR, and D_MTPERMOD
* specifying that the callback i.e qtimeout() procedures should
* not be single-threaded at the inner perimeter.
* _D_MTSVCSHARED - EXPERIMENTAL - will be removed in a future release.
* Modifier for D_MTPERMOD only. Specifies that the service
* procedure should not be single-threaded at the inner perimeter.
* However only a single instance of the service thread can run on
* any given queue.
* D_MTOCEXCL - modifier for D_MTOUTPERIM specifying that the open and
