[ Upstream commit 308c6cafde0147616da45e3a928adae55c428deb ] There are two test cases: 1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio, and install them again, must use "ifconfig down/ifconfig up" command pair to bring port to work. This patch calls phy_stop function when init phy to fix this bug. 2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again, all ports can not use anymore, because of the phy devices register failed(phy devices already exists). Phy devices are registered when hns_dsaf installed, this patch removes them when hns_dsaf removed. The two cases are sometimes related, fixing the second case also requires fixing the first case, so fix them together.

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.
