Jiri Pirko 5f18426928 netdev: expose DPLL pin handle for netdevice ... In case netdevice represents a SyncE port, the user needs to understand the connection between netdevice and associated DPLL pin. There might me multiple netdevices pointing to the same pin, in case of VF/SF implementation. Add a IFLA Netlink attribute to nest the DPLL pin handle, similar to how it is implemented for devlink port. Add a struct dpll_pin pointer to netdev and protect access to it by RTNL. Expose netdev_dpll_pin_set() and netdev_dpll_pin_clear() helpers to the drivers so they can set/clear the DPLL pin relationship to netdev. Note that during the lifetime of struct dpll_pin the pin handle does not change. Therefore it is save to access it lockless. It is drivers responsibility to call netdev_dpll_pin_clear() before dpll_pin_put().
