Hi everyone,

I wrote a simple loop back application and measured latency at low load 
around 1Kpps.  I am experiencing severe extra latency at median around 
2-4us when crossing PCI-e.

This is not the case for connectx5 cards. I am wondering if anybody else 
noticed this issue or not, and if there is fix.

Thanks,
Alireza
