* The table is used for classifying incoming packets in software.
*
* The protection scheme uses 2 elements, a coarse serialization mechanism

*
* The protection scheme for each member of the mac_impl_t is described below.

* data structure. For example something in mac_impl_t that stays the same
* from mac_register to mac_unregister, or something in a mac_client_impl_t
* that stays the same from mac_client_open to mac_client_close.
*
* Serializer (SL): Protected by the Serializer. All SLOP operations on a
* mac endpoint go through the serializer. MTOPs don't care about reading
* these fields atomically.
*
* Lock: Traditional mutex/rw lock. Modify operations still go through the
* mac serializer, the lock helps synchronize readers with writers.
