        !            24: .SH SYNOPSIS
        !            25: .B "device np0 at uba0 csr 166000 vector npintr"
        !            26: .SH DESCRIPTION
        !            27: The
        !            28: .I NP
        !            29: device provides access to an Interlan Np100 Ethernet interface
        !            30: for control functions.
        !            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 link-level interface.
        !            34: This is accomplished by opening a character special device,
        !            35: and writing data to it.
        !            36: It is also possible to do post-mortem debugging of firmware failures
        !            37: by reading the local memory of the device.
        !            38: .PP
        !            39: A program to load the image is provided in /usr/src/new/np100.
        !            40: The sequence of commands would be:
        !            41: .nf
        !            42: 
        !            43:        # ./npload np.image [/dev/np00]
        !            44:        # sleep 10
        !            45:        # ifconfig ix0 ...
        !            46: .fi
        !            47: .PP
        !            48: Multiple control processes are allowed by opening separate
        !            49: minor devices; secondary interfaces are specified by shifting
        !            50: the interface number by 4 bits.
        !            51: .PP
        !            52: The device also responds to commands passed through the driver
        !            53: by the following ioctls:
        !            54: .TP
        !            55: NPRESET
        !            56: .br
        !            57: kills off all active network processes.

        !            60: .br
        !            61: begins execution of the board at the specified address (usually 0x400).
        !            62: .TP
        !            63: NPNETBOOT
        !            64: .br
        !            65: downloads the image from a server on the network.
