Hello Maxim,
after disabling FDIR what's the pps rate you are getting from you 24 
core system?

You made a lot of tuning of the network driver while searching a 
solution to this problem. Could you share all the relevant settings of 
the ixgbe driver from /boot/loader.conf and /etc/sysctl.conf?

I'm trying to fine tune the settings on a 16 core system but I have some 
doubt so I'd like to compare my settings with yours.

I'm working on a high PPS router and I'm also interested to Luigi 
Rizzo's netmap code. I tried netmap with click for forwarding but 
unfortunately I'm facing some problem with route pushing from quagga. I 
had also to understand if is possible to link aggregate two ixgbe with 
netmap (using lacp).

Thanks in Advance,
Davide
