        !            23: ix \- Interlan Np100 10 Mb/s Ethernet interface
        !            24: .SH SYNOPSIS
        !            25: .B "device np0 at uba0 csr 166000 vector npintr"
        !            26: .SH DESCRIPTION
        !            27: The
        !            28: .I ix
        !            29: interface provides access to a 10 Mb/s Ethernet network through
        !            30: an Interlan Np100 controller used as a link-layer interface.
        !            31: .PP
        !            32: This interface is unusual in that it requires loading firmware
        !            33: into the controller before it may be used as a network interface.
        !            34: This is accomplished by opening a character special device,
        !            35: and writing data to it.
        !            36: A program to load the image is provided in /usr/src/new/np100.
        !            37: The sequence of commands would be:
        !            38: .nf
        !            39: 
        !            40:        # ./npload np.image [/dev/np<board #> if other than np00]
        !            41:        # sleep 10
        !            42:        # ifconfig ix0 ...
        !            43: .fi
        !            44: .PP
        !            45: Each of the host's network addresses
        !            46: is specified at boot time with an SIOCSIFADDR
        !            47: ioctl.  The
        !            48: .I ix
        !            49: interface employs the address resolution protocol described in
        !            50: .IR arp (4)
        !            51: to dynamically map between Internet and Ethernet addresses on the local
        !            52: network.
        !            53: .PP
        !            54: The interface normally tries to use a ``trailer'' encapsulation
        !            55: to minimize copying data on input and output.
        !            56: The use of trailers is negotiated with ARP.
        !            57: This negotiation may be disabled, on a per-interface basis,
        !            58: by setting the IFF_NOTRAILERS
        !            59: flag with an SIOCSIFFLAGS ioctl.
        !            60: .SH DIAGNOSTICS
        !            61: \fBix%d: Req failed, cmd %x, stat %x, ust error %x,%x\fP.
        !            62: The firmware in the controller refused to honor a request from
        !            63: .UX
        !            64: in initializing packet level communications.
        !            65: The board may need to be reset and reloaded.
        !            66: Or, you may not have allowed enough time between loading the board
        !            67: and issuing the request to begin unix network operation.
        !            68: .PP
        !            69: \fBix%d: can't initialize\fP.
        !            70: The interface was unable to obtain unibus resources required for operation.

        !            72: \fBix%d: failed to reinitialize DLA module\fP.
        !            73: The interface got sick after attempting to reprogram its physical
        !            74: ethernet address.  Try reloading the firmware.
        !            75: The attempt is made only when this interfaces is not the first
        !            76: one configured for XNS.

        !            78: \fBix%d: can't handle af%d\fP.  The interface was handed
        !            79: a message with addresses formatted in an unsuitable address
        !            80: family; the packet was dropped.
        !            81: .PP
        !            82: \fBix%d: stray xmit interrupt, npreq=%x\fP.
        !            83: This may happen if the board is reloaded while network processes are still
        !            84: running.
        !            85: .PP
        !            86: \fBixrint: cqe error %x, %x, %x\fP.
        !            87: This will result if an 
        !            88: .IR ifconfig (8c)
        !            89: request is made at an inopportune time, such as not allowing
        !            90: enough time after loading the firmware.
        !            91: After 100 such errors are logged, the unix network driver will
        !            92: shut itself down, saying:
        !            93: .PP
        !            94: \fBixrint: shutting down unix dla\fP.
        !            95: The recourse is to reload the firmware and allow more time.
