fza(4) Kernel Interfaces Manual fza(4) Name fza - DEFZA FDDI Network Interface Syntax device fza0 at ibus? vector fzaintr Description The interface is a high speed TURBOchannel bus to a 100 Mbit/second Fiber Distributed Data Interface (FDDI) timed token ring network adapter. The interface allows the host system to be an FDDI single attachment station. The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl. The interface employs the address resolution protocol described in to map dynamically between Internet and FDDI addresses on the local network. The maximum frame size for the interface is 4500 bytes, which is substantially larger that the 1500 bytes maximum packet size of the Ether- net interfaces. The interface does not support the BSD trailer encapsulation, which is specific to the VAX architecture. The SIOCRPHYSADDR ioctl can be used to read the physical address of the DEFZA adapter. The physical address of the DEFZA adapter can not be changed. The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete multicast addresses. The DEFZA supports up to 64 multicast addresses. The SIOCRDCTRS ioctl can be used to read the FDDI driver counters. The DEFZA adapter status and characteristics can also be read through this ioctl by providing a FDDI_STATUS flag . The argument to this ioctl is a pointer to a counter or status structure, found in <net/if.h>. The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode, respectively. The SIOCEEUPDATE ioctl can be used to update the adapter's firmware. The SIOCIFRESET ioctl can be used to reset the adapter. Diagnostics Diagnostic error messages contain information provided by the driver. For example: fza%d: fzaprobe selftest failed The DEFZA adapter did not pass the power-up selftest during autoconfiguration. fza%d: port init failed The DEFZA adapter cannot be initialized. fza%d: port in the Halt State -> CNS hardware fault The DEFZA adapter went to the Halt state because of an adapter firmware fault. fza%d: LINK unavailable The network link went down which means that the station is not on the FDDI ring. fza%d: Ring Init Received A Ring Initialization unsolicited event has been received from the fza%d interface.
