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 ...
