Hello Adrian, I wonder if the current RSS code supports software mode. Is it possible to enforce software RSS? And what about Sender Side Scaling ?
I want to assign a snort instance for each NIC queue. Snort is configured to use netmap mode. Needs and questions are below: - For a proper detection, both of request and response packets must enter into same snort instance so that same NIC queue. For example 3way handshake packets, TLS handshake packets and etc all must use same queue for both directions. - I'm afraid that, option RSS is only socket aware. But gateways/routers doesnt have sockets for all connections. Is it possible to perform such hashing and requeuing while forwarding packets? - On receive side, is it possible to hashing & requeuing before the netmap step? - On sender side, is it possible to hashing & queuing before pushing in NIC queue? What is the right way to do this?
