From 1fd6e7c10c779aa31d3999a10e3a126df26eb7b9 Mon Sep 17 00:00:00 2001 From: Maximilian Luz Date: Thu, 16 May 2019 17:08:31 +0200 Subject: [PATCH] USB: Add LPM quirk for Surface Dock GigE adapter commit ea261113385ac0a71c2838185f39e8452d54b152 upstream. Without USB_QUIRK_NO_LPM ethernet will not work and rtl8152 will complain with r8152 : Stop submitting intr, status -71 Adding the quirk resolves this. As the dock is externally powered, this should not have any drawbacks.
