| Subject: usb: quirks: add NO_LPM quirk for RTL8153 based ethernet adapters |
| |
| From: Hans de Goede <hdegoede@redhat.com> |
| |
| commit 75d7676ead19b1fbb5e0ee934c9ccddcb666b68c upstream. |
| |
| We have been receiving bug reports that ethernet connections over |
| RTL8153 based ethernet adapters stops working after a while with |
| errors like these showing up in dmesg when the ethernet stops working: |
| |
| [12696.189484] r8152 6-1:1.0 enp10s0u1: Tx timeout |
| [12702.333456] r8152 6-1:1.0 enp10s0u1: Tx timeout |
| [12707.965422] r8152 6-1:1.0 enp10s0u1: Tx timeout |
| |
| This has been reported on Dell WD15 docks, Belkin USB-C Express Dock 3.1 |
| docks and with generic USB to ethernet dongles using the RTL8153 |
| chipsets. Some users have tried adding usbcore.quirks=0bda:8153:k to |
| the kernel commandline and all users who have tried this report that |
| this fixes this. |
| |
| Also note that we already have an existing NO_LPM quirk for the RTL8153 |
| used in the Microsoft Surface Dock (where it uses a different usb-id). |
| |
| This commit adds a NO_LPM quirk for the generic Realtek RTL8153 |
| 0bda:8153 usb-id, fixing the Tx timeout errors on these devices. |
