    This one of the main reasons to 'go netgraph'. In fact, the actual
    ueagle driver uses NATM.

    But noted strong differences between atm boards and adsl modems.

    - atm boards are hardware assisted. usb adsl modems are bare assisted.

    - atm boards support better signaling, multiple channels, ... usb adsl
    modems just one PVC with uni signaling.

    So I realize that try to get a NATM/NETGRAPH hardware driver may be too
    work for little gain.

    Right now, I think that maintain a ng_uadsl closer enough to ng_atm must
    be a better solution.

    In other words, take harti work as a reference, but let uadsl
    independent of atm works.
