rns_smt - Rockwell Station Management driver
On the Rockwell FDDI adapter boards, the rns_smt driver
implements the FDDI Station Management protocol ( SMT ). The
Station Management protocol includes Connection Management,
Ring Management and all frame services. The rns_snt driver
is a loadable, clonable STREAMS driver that can support
multiple instances of the FDDI interface, as well as multi-
ple application layer clients.
The cloning character-oriented devices /dev/rns_smt are used
to access the rns_snt driver that supports Rockwell FDDI
The /dev/rns_smt device is an interface used only for Sta-
tion Management applications, such as those that gather MIB
statistics or other Station information.
The SMT driver supports DLPI and SPI interfaces. All
M_PROTO and M_PCPROTO type messages are interpreted as DLPI
or SPI. SPI ( SMT provider interface) is a Rockwell
proprietary interface that is used during communication
between the SMT and related applications. rns_smt is a
"style 2" data link service provider, which means that an
explicit DL_ATTACH_REQ is required to associate the opened
stream with a particular device or physical point of attach-
ment ( PPA ).
