From 11ac4e668a449af328379f9fb2e1712357d2eca5 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 15 Apr 2021 20:59:47 +0200 Subject: [PATCH] r8169: keep pause settings on interface down/up cycle Currently, if the user changes the pause settings, the default settings will be restored after an interface down/up cycle, and also when resuming from suspend. This doesn't seem to provide the best user experience. Change this to keep user settings, and just ensure that in jumbo mode pause is disabled. Small drawback: When switching back mtu from jumbo to non-jumbo then pause remains disabled (but user can enable it using ethtool). I think that's a not too common scenario and acceptable.
