Working towards obsoleting the .ndo_do_ioctl operation entirely, stop passing the SIOCBRADDIF/SIOCBRDELIF device ioctl commands into this callback. My first attempt was to add another ndo_siocbr() callback, but as there is only a single driver that takes these commands and there is already a hook mechanism to call directly into this driver, extend this hook instead, and use it for both the deviceless and the device specific ioctl commands.
