usb: quirks: add NO_LPM quirk for RTL8153 based ethernet adapters
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.
