[ Upstream commit a07f23ad9baf716cbf7746e452c92960536ceae6 ] Lenovo ThinkPad Hybrid USB-C with USB-A Dock (17ef:a359) is affected by the same problem as the Lenovo Powered USB-C Travel Hub (17ef:721e): Both are based on the Realtek RTL8153B chip used to use the cdc_ether driver. However, using this driver, with the system suspended the device constantly sends pause-frames as soon as the receive buffer fills up. This causes issues with other devices, where some Ethernet switches stop forwarding packets altogether. Using the Realtek driver (r8152) fixes this issue. Pause frames are no longer sent while the host system is suspended.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
