For example, e6000sw creates such struct ifnets for each of its ports so it can call into the MII code. If there is then a link state event this calls do_link_state_change() -> rtnl_handle_ifevent() -> dump_iface() -> get_operstate() -> get_operstate_ether(). That wants to know if the link is up or down, so it tries to ioctl(SIOCGIFMEDIA), which doesn't go well if if_ioctl is NULL. Guard against this, and return EOPNOTSUPP.
