    ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts · 70093cfd
    Stefan Richter 提交于
    Until now, ieee1394 put an IP-over-1394 capability entry into each new
    host's config ROM.  As soon as the controller was initialized --- i.e.
    right after modprobe ohci1394 --- this entry triggered a hotplug event
    which typically caused auto-loading of eth1394.
    
    This irritated or annoyed many users and distributors.  Of course they
    could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
    1394 capability to the FireWire bus.
    
    Therefore
      - remove the offending kernel config option
        IEEE1394_CONFIG_ROM_IP1394,
      - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
        loaded.
    
    This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .
    
    To emulate the behaviour of older kernels, simply add the following to
    to /etc/modprobe.conf:
    
    install ohci1394 /sbin/modprobe eth1394; \
                     /sbin/modprobe --ignore-install ohci1394
    
    Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
    device is discovered is _not_ affected by this patch.
