Description
AF_XDP has grown considerably in functionality and hardware support, but recent netdev discussions have exposed gaps in semantics, queue lifecycle, offloads, and cross-driver testing. This BoF is intended to align on the main pain points and identify concrete next steps.
Topics can, e.g., be:
- AF_XDP semantics: copy vs zero-copy, multi-buffer, UMEM constraints
- TX/RX metadata and offloads
- Queue ownership, RSS contexts, netkit queue leasing
- Driver capability discovery and consistency
- xskxceiver gaps and AF_XDP hardware compliance testing
- Running AF_XDP tests in drivers/net/hw / NIPA CI
- Open issues and next steps
