        !            26: .SH DESCRIPTION
        !            27: The
        !            28: .I hy
        !            29: interface provides access to a Network
        !            30: Systems Corporation Hyperchannel Adapter.
        !            31: .PP
        !            32: The network to which the interface is attached
        !            33: is specified at boot time with an SIOCSIFADDR ioctl.  
        !            34: The host's address is discovered by reading the adapter status
        !            35: register.  The interface will not transmit or receive
        !            36: packets until the network number is known.
        !            37: .SH DIAGNOSTICS
        !            38: \fBhy%d: unit number 0x%x port %d type %x microcode level 0x%x\fP.
        !            39: Identifies the device during autoconfiguration.
        !            40: .PP
        !            41: \fBhy%d: can't handle af%d\fP.  The interface was handed
        !            42: a message with addresses formatted in an unsuitable address
        !            43: family; the packet was dropped.

        !            45: \fBhy%d: can't initialize\fP.
        !            46: The interface was unable to allocate UNIBUS resources. This
        !            47: is usually due to having too many network devices on an 11/750
        !            48: where there are only 3 buffered data paths.
        !            49: .PP
        !            50: \fBhy%d: NEX - Non Existent Memory\fP.
        !            51: Non existent memory error returned from hardware.

        !            56: \fBhy%d: Power Off bit set, trying to reset\fP.
        !            57: Adapter has lost power, driver will reset the bit
        !            58: and see if power is still out in the adapter.
        !            59: .PP
        !            60: \fBhy%d: Power Off Error, network shutdown\fP.
        !            61: Power was really off in the adapter, network
        !            62: connections are dropped.
        !            63: Software does not shut down the network unless
        !            64: power has been off for a while.
        !            65: .PP

        !            67: A message proper was received that is too big.
        !            68: Probable a driver bug.
        !            69: Shouldn't happen.

        !            79: \fBhy%d: watchdog timer expired\fP.
        !            80: A command in the adapter has taken too long to complete.
        !            81: Driver will abort and retry the command.
        !            82: .PP
        !            83: \fBhy%d: adapter power restored\fP.
        !            84: Software was able to reset the power off bit,
        !            85: indicating that the power has been restored.
        !            86: .SH SEE ALSO
        !            87: netintro(4), inet(4)
        !            88: .SH BUGS
        !            89: If the adapter does not respond to the status command
        !            90: issued during autoconfigure, the adapter is assumed down.
        !            91: A reboot is required to recognize it.
        !            92: .PP
        !            93: The adapter power fail interrupt seems to occur
        !            94: sporadically when power has, in fact, not failed.
        !            95: The driver will believe that power has failed
        !            96: only if it can not reset the power fail latch after
        !            97: a ``reasonable'' time interval.
        !            98: These seem to appear about 2-4 times a day on some machines.
        !            99: There seems to be no correlation with adapter
        !           100: rev level, number of ports used etc. and whether a
        !           101: machine will get these ``bogus powerfails''.
        !           102: They don't seem to cause any real problems so they have
        !           103: been ignored.
