ieee1394: limit early node speed to host interface speed
The following patch limits the node speed to the host interface speed, before using it. Signed-off-by: Philippe De Muyter <phdm@macqel.be> It should actually suffice to do this only for the local node's speedcap[]. But there is another bug in the speed calculation: The local node's speed is not correctly propagated to the speeds which are to be used to access remote nodes. http://thread.gmane.org/gmane.linux.kernel.firewire.devel/11772/focus=12024 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
