Hi Xiaowei,

No, unfortunately.  Even in our early papers, when we measured "Polling Linux", 
we essentially used Click elements on the edges (& passed the packets to Linux 
right away).  However the e1000 *does* have a Linux polling driver on 2.6; it 
uses the new "NAPI" driver interface.  According to other recent mail it's a bit 
slower than Click.
