However, all of these only support a single device, and they completely ignore the command line settings from netdev_boot_setup_check, so there is really no point at all. Aside from sun3_82586, these already have a module_init function that can be used for built-in mode as well, simply by removing the #ifdef. Note that the 82596 driver was previously used on ISA as well, but that got dropped long ago.
