[ Upstream commit5c968f4802] mii_nway_restart is not pm aware which results in a rtnl deadlock. Implement mii_nway_restart manual by setting BMCR_ANRESTART if BMCR_ANENABLE is set. To reproduce: * plug an asix based usb network interface * wait until the device enters PM (~5 sec) * `ip link set eth1 up` will never return Fixes:d9fe64e511("net: asix: Add in_pm parameter") Signed-off-by: Alexander Couzens <lynxis@fe80.eu> Signed-off-by: David S.

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.
