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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
