The wrsmd device driver is a pseudo driver that presents
a type II DLPI interface. The driver uses a Sun proprietary
interface over the wrsm driver to provide IP-based communication
over the WCI network.
Before using DLPI over a WCI network, you must first
configure the wrsm controller on that network. See wrsmconf(1M) for
more information. Each wrsmd device is associated with
a wrsm controller with a matching id.
