DPDK transformed wired networking by giving host software direct control over packet processing. This talk makes the case that the same approach should be applied to 802.11 wireless.
Wi-Fi’s real behavior—contention, TXOP scheduling, A-MPDU aggregation, rate adaptation, and retries—is hidden below the 802.3 interface inside firmware and hardware state machines. This prevents per-packet observability and programmable control.
We propose a Wi-Fi Poll Mode Driver model that operates natively on 802.11 frames, exposing aggregation and retry behavior as first-class metadata and accepting explicit transmission parameters (MCS/NSS/BW, TXOP limits, retry policy). With this interface, a DPDK application can coordinate microsecond-scale MAC scheduling with millisecond-scale ECN/AQM control.
We outline the required PMD interface, metadata surface, and driver hooks needed to bring software-defined control to wireless networking.
