the nice folks at cloudflare implemented a nice feature in netmap that puts some queues of the NIC in netmap mode leaving others attached to the host stack https://blog.cloudflare.com/single-rx-queue-kernel-bypass-with-netmap/ and use ethtool (and native NIC filters) to steer traffic around. [FWIW, the chelsio native netmap driver is similar except that the netmap queue has a different MAC address] While their code was developed on linux, it should run almost unmodified on FreeBSD (and we plan to import it soon), except for the fact that we don't have ethtool hence no device-independent mechanism to configure traffic steering. We really need to address the latter. cheers luigi -- -----------------------------------------+------------------------------- Prof. Luigi RIZZO, rizzo_at_iet.unipi.it .
