+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.
