Subject: [PATCH] r8169: disable interrupt source RxOverflow
Vendor driver calls this bit RxDescUnavail. All we do in the interrupt
handler in this case is scheduling NAPI. If we should be out of
RX descriptors, then NAPI is scheduled anyway. Therefore remove this
interrupt source. Tested on RTL8168h.
