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 7 =================== In this week I've explored the FreeBSD code that deals with virtio-net headers and related offloadings, so that I could start to incorporate them into the ptnet driver. Together with various code improvements, I started to implement virtio-net-header-aware datapath, both for the TX and RX side. Next week will be used to complete the virtio-net header support and start testing them through the QEMU hypervisor.
