somethign with this? or point me to the proper person for this? 
THanks:-)

State-Changed-When: Wed Jun 6 18:48:02 UTC 2007 
State-Changed-Why:  
After a little discussion between Yongari and Bruce the concensus was 
reached that adding this to sk is not profitable. Cases where POLLING 
was used had more latency and have bad throughput, so we are sorry but 
we are not going to add the POLLING facility to sk(4).

 Hello,
 
 Can you clear this up? I'm a little confused.
 
 Is polling causing latency to all nics? and we are advised to not use it?
