    Subject[PATCH 4.14 31/69] USB: Add LPM quirk for Surface Dock GigE adapter
    Date
    From: Maximilian Luz <luzmaximilian@gmail.com>

    commit ea261113385ac0a71c2838185f39e8452d54b152 upstream.

    Without USB_QUIRK_NO_LPM ethernet will not work and rtl8152 will
    complain with

    r8152 <device...>: Stop submitting intr, status -71

    Adding the quirk resolves this. As the dock is externally powered, this
    should not have any drawbacks.
