    hsr: use netdev_master_upper_dev_link() when linking lower ports

    Unlike VLAN devices, HSR changes the lower device’s rx_handler, which
    prevents the lower device from being attached to another master.
    Switch to using netdev_master_upper_dev_link() when setting up the lower
    device.

    This could improves user experience, since ip link will now display the
    HSR device as the master for its ports.
