    net: core: dev: Add extack argument to dev_change_flags()

    In order to pass extack together with NETDEV_PRE_UP notifications, it's
    necessary to route the extack to __dev_open() from diverse (possibly
    indirect) callers. One prominent API through which the notification is
    invoked is dev_change_flags().

    Therefore extend dev_change_flags() with and extra extack argument and
    update all users. Most of the calls end up just encoding NULL, but
    several sites (VLAN, ipvlan, VRF, rtnetlink) do have extack available.

    Since the function declaration line is changed anyway, name the other
    function arguments to placate checkpatch.

This patch backports the above upstream patch and also adds fixes
in compat code.
