parentnet: phylink: Add phylink_mac_link_{up, down} wrapper functions (diff)
net: phylink: Add struct phylink_config to PHYLINK API
The phylink_config structure will encapsulate a pointer to a struct device and the operation type requested for this instance of PHYLINK. This patch does not make any functional changes, it just transitions the PHYLINK internals and all its users to the new API. A pointer to a phylink_config structure will be passed to phylink_create() instead of the net_device directly. Also, the same phylink_config pointer will be passed back to all phylink_mac_ops callbacks instead of the net_device. Using this mechanism, a PHYLINK user can get the original net_device using a structure such as 'to_net_dev(config->dev)' or directly the structure containing the phylink_config using a container_of call. At the moment, only the PHYLINK_NETDEV is defined as a valid operation type for PHYLINK. In this mode, a valid reference to a struct device linked to the original net_device should be passed to PHYLINK through the phylink_config structure. This API changes is mainly driven by the necessity of adding a new operation type in PHYLINK that disconnects the phy_device from the net_device and also works when the net_device is lacking.
