When a netdev (PF netdev or representor) is opened or closed, set the physical port config bit appropriately - which powers UP/DOWN the PHY module for the physical interface. The PHY is powered first in the HW/FW configuration step when opening the netdev and again last in the HW/FW configuration step when closing the netdev. This is only applicable when there is a physical port associated with the netdev and if the NSP support this. Otherwise we silently ignore this step. The 'nfp_eth_set_configured' can actually return positive values - updated the function documentation appropriately.

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.
