Thanks Jeff!

The original tulip patch was done by Alexey and came w. the NAPI kernel patch.
And the interrupt mitigation part was stolen and simplified from Jamal. :-)


BTW. I'm hacking with a userland app to get interface stats. It's fork of a
Alexey program too. ifstat. In my take it's ifstat2 and looks like:

 
ifstat2 eth*
             RX --------------------------   TX -------------------------
eth0          704.9 M bit/s       59 k pps      3.2 M bit/s        5 k pps 
eth1             16   bit/s        0   pps    215.8 k bit/s      431   pps 
eth2          220.8 k bit/s      441   pps        0   bit/s        0   pps 
eth3              0   bit/s        0   pps    219.5 k bit/s      438   pps

It's fits between ip -s link and ethtool -S
