    [Previously posted to -net in another form.]

    I propose to add an if_dev member to struct ifnet. It would be of type
    device_t and be defined to point to the device for the interface or NULL
    if there is no device (or if there was not an easy way to get access to
    one).

    This change would codify the the relationship between an interface and
    the underlying physical device. It also would get rid of the existing
    abuses of if_name to look up the driver associated with an interface
    and simplify a number of messy cases in the conversion from if_unit and
    if_name to if_xname.

    Does this seem like a reasonable thing to do?
