    Subjectdrivers between net-device and char-device
    I am assigned (a dream coming true!) the task of writing a device-driver
    for a bitbus board. The hardware developer is willing to support me as
    well as a guy who wrote the driver for NT.

    I read Alessandro's LINUX DEVICE DRIVERS, did not understand everything
    and started coding.

    The bitbus (anybody know it?) is a packet-oriented thing very much like
    RS 485. Plus it has a protocol on top like IP. For better usability the
    vendor of the micro-OS we use added another protocol on top of that like

    Now, if I wanted to do it RIGHT (in the sence of perfect) I would need
    to implement the two protocol layers for the Linux-Kernel and a
    net-device-driver for the board, right?

    I know that this would be to big a step. Since I want to get somewhere
    soon I thought that I first do it as a simple char-device.

    But since I have packages anyway, I started to use the ne.c source as a
    start. Everything seems to fit well, but I can not use the
    ethernet-structure in my char-driver because that would mean that I need
    any type of protocol, right? So I got stuck inbetween a net and a char
    device. Is there a way to use net-structures without protocols in

    And a general question: I do have problems understanding some concepts
    in drivers. Is this list the right place to ask?
