[parisc-linux] Lan configuration failures

[John Marvin]

Today some people have seen a couple of failures using the new ram disk
that willy generated. This new ram disk contains a program that tries
to configure a network card.  I have tracked down the problems, and
found them to both be configuration related:

    1) First, you must have CONFIG_INET set. If you don't, the socket
    call will fail, and you will get a "Bad file number" failure,
    due to the code trying to do an ioctl call on the -1 returned
    from the socket call failure.

    2) You must have the tulip driver configured in (CONFIG_DEC_ELCP)
    which also requires things like CONFIG_PCI, etc. If you have
    an older box that does not contain a tulip based network interface,
    or if you have a newer non Lasi box, you will not be able to
    get this to work. You must see "eth0:" debug output.

    If the hardware is not configured properly, the socket call will
    succeed, however the following ioctl will fail and you will get
    a "No such device" error.

Both of the failures will lead to the program exiting, which finally
will result in a "Kernel panic: Attempted to kill init!" failure.
