Description

AF_XDP is a relatively novel packet family which builds on top of XDP and supports directly accessing low-level networking queues from userspace. It exposes raw packet headers and payload and bypasses most of the kernel stack. Recently, it gained the support of NIC receive-side offloads and I'm actively working on exposing the transmit-side offloads as well. In this talk, I'll expand more on what has been done so far and what the future looks like.
