Ok, I will try to explain it ... I am doing some tests with this FreeBSD 
kvm guest to act as a IDS.

After changing some kernel network related options like 
net.inet.tcp.recvspace, net.inet.tcp.sendspace, 
net.inet.tcp.sendbuf_max, etc ... I am loosing too much packets ... Yes 
I know it: due to I am using this freebsd host as a virtualized guest I 
can't expect really good results ... but I have another linux 
virtualized host using pf_ring, and I don't lose too much packets. The 
main difference is that in the linux server I configured 
"enable_tx_capture=0" and "min_num_slots=65535" in pf_ring's module.

For this reason, I am thinking if it is possible to accomplish same or 
similar type of configuration in netmap ...
