Network Interface Tap

The Network Interface Tap (NIT) provided in the SunOS 4.x release is no longer required. Now Ethernet drivers are real STREAMS drivers that can be opened and communicated with directly.

See pfmod(7M), bufmod(7M), and dlpi(7P)

The Solaris 7 Ethernet drivers and other data link drivers support the connectionless Data Link Provider Interface (DLPI) Version 2 specification.
