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.
