Hello Project summary ================= ptnet is a new multi-queue paravirtualized device that builds on ptnetmap to allow VMs to exchange TCP traffic at 20 Gbps, while still offering the same ptnetmap performance (10-100 Mpps) to native netmap applications. The purpose of this SOC project is to write a ptnet driver for FreeBSD and a corresponding device model for the bhyve hypervisor. Status update for week 4 =================== I've started to extend the ptnet driver, implementing the network interface methods: the ioctl routine (IFF_UP/IFF_DOWN, ...), the transmission routine and reception routine, together with interrupt handling. Plan for week 5 is to complete the implementation (add per-queue taskqueues, complete ioctl, revise TX/RX routines), so that experimentation and bug-fixing can start in week 6.
