Hi,

I continued improving the the performance patches which results in the first 
usable version. I tested it in a VM environment as well as on real hardware 
and did not encounter problematic behavior anymore. 

Changes since v1:
* code rebased on top of the trunk
* orig_node NULL pointer dereference fixed (thanks Linus)
* bcast_own / bcast_own_sum are now protected by a spinlock
* orig_node reference count had to be increased in transtable_search()

Known issues:
* bonding / alternating candidates are not secured by refcounting [see  
find_router()] - ideas welcome

Give this code a try and let me know what you find.

Regards,
Marek
