NAME

       usoc - universal serial optical controller for Fibre Channel arbitrated loop (SOC+) device driver

DESCRIPTION

       The  Fibre  Channel adapter is an SBus card that implements two full duplex Fibre Channel interfaces. Each interface can connect to a Fibre
       Channel arbitrated loop (FC-AL). The usoc device driver is a nexus driver and implements portions of the FC-2 and FC-4 layers of FC-AL.
