net: usb: aqc111: Various callbacks implementation
Reset, stop callbacks, driver unbind callback. More register defines required for these callbacks. Add helpers to read/write 16bit values Signed-off-by: Dmitry Bezrukov <dmitry.bezrukov@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.
