From 94bc1e522b32c866d85b5af0ede55026b585ae73 Mon Sep 17 00:00:00 2001 From: Lyude Paul Date: Thu, 22 Aug 2019 14:33:18 -0400 Subject: [PATCH 1/7] igb/igc: Don't warn on fatal read failures when the device is removed Fatal read errors are worth warning about, unless of course the device was just unplugged from the machine - something that's a rather normal occurrence when the igb/igc adapter is located on a Thunderbolt dock. So, let's only WARN() if there's a fatal read error while the device is still present. This fixes the following WARN splat that's been appearing whenever I unplug my Caldigit TS3 Thunderbolt dock from my laptop: igb 0000:09:00.0 enp9s0: PCIe link lost ------------[ cut here ]------------ igb: Failed to read reg 0x18!

This patch enables the hardware feature "Media Auto Sense" also on the i350. It works in the same way as on the 82850 devices.

If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.
