From ec9a40881732c834fe7ffe224981a35043e6a725 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Mon, 10 Jun 2019 18:21:50 +0200 Subject: r8169: improve setting interrupt mask So far several places in the code deal with setting the interrupt mask for the respective chip versions. Improve this by having one function for this only. In addition don't set RxFIFOOver for all 8101 chip versions like in the vendor driver. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
