>Description:
If polling is enabled network on fwip interface stops working after you try
to transfer a large file over it. After that even ping doesn't work. Only
solution is to reboot.
I have not tested fwe (ethernet over firewire) interface, but it might have
the same problem.
	
>How-To-Repeat:
Try transfering a large file over fwip interface with polling enabled using above configuration.
	
>Fix:
Don't enable polling until this is resolved.
