Some netlink commands are target towards ethernet PHYs, to control some of their features. As there's several such commands, add the ability to pass a PHY index in the ethnl request, which will populate the generic ethnl_req_info with the passed phy_index. Add a helper that netlink command handlers need to use to grab the targeted PHY from the req_info. This helper needs to hold rtnl_lock() while interacting with the PHY, as it may be removed at any point.
