From 6994520a332887f1688464f250c9ec8002a89a8e Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Mon, 27 May 2024 21:16:56 +0200 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.
