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.

IEEE 1394 describes a high performance serial bus, which is also
|
|
known as FireWire(tm) or i.Link(tm) and is used for connecting all
|
|
sorts of devices (most notably digital video cameras) to your
|
|
computer.
|
|
|
|
If you have FireWire hardware and want to use it, say Y here. This
|
|
is the core support only, you will also need to select a driver for
|
|
your IEEE 1394 adapter.
|
|
|
|
To compile this driver as a module, say M here: the
|
|
module will be called ieee1394.

If you say Y here, you will get very verbose debugging logs from
|
|
the subsystem which includes a dump of the header of every sent
|
|
and received packet. This can amount to a high amount of data
|
|
collected in a very short time which is usually also saved to
|
|
disk by the system logging daemons.
|
|
|
|
Say Y if you really want or need the debugging output, everyone
|
|
else says N.

Enable this driver if you have an IEEE 1394 controller based on the
|
|
OHCI-1394 specification. The current driver is only tested with OHCI
|
|
chipsets made by Texas Instruments and NEC. Most third-party vendors

use one of these chipsets. It should work with any OHCI-1394
|
|
compliant card, however.

This builds sbp2 for use with non-OHCI host adapters which do not

Physical DMA is data movement without assistance of the drivers'

interrupt handlers. This option includes the interrupt handlers

that are required in absence of this hardware feature.

This option is buggy and currently broken on some architectures.

This driver implements a functional majority of RFC 2734: IPv4 over
|
|
1394. It will provide IP connectivity with implementations of RFC
|
|
2734 found on other operating systems. It will not communicate with
|
|
older versions of this driver found in stock kernels prior to 2.6.3.
|
|
This driver is still considered experimental. It does not yet support
|

MCAP, therefore multicast support is significantly limited.
