does freebsd support so called Scalable I/O on intel NIC ?

[Bartosz Giza]

Hi,

i am looking for a good NIC from NIC to put on our quite busy router based 
on freebsd 6.3 (soon 7.x)
I've found server NIC from intel and there is such a thing like scalable I/O 
on windows and linux.
(from web page)

"load balancing on multiple CPUs Increases
performance on multi-processor systems by efficiently
balancing network loads across CPU cores when used
with Receive-Side Scaling from Microsoft or Scalable
 I/O on Linux*"

Is such thing supported on freebsd ?

And one more question. Does anybody has some data what is difference on 
desktop and server NIC from INTEL in pps or so.
I wonder how faster could be those server NICs

thanks
