This series is intended as a playground to start experimenting/developing with XDP/eBPF over WiFi and collect ideas/concerns about it. Introduce XDP support to mt76x2e/mt76x0e drivers. Currently supported actions are: - XDP_PASS - XDP_ABORTED - XDP_DROP Introduce ndo_bpf mac80211 callback in order to to load a bpf program into low level driver XDP rx hook. This series has been tested through a simple bpf program (available here: https://github.com/LorenzoBianconi/bpf-workspace/tree/master/mt76_xdp_stats) used to count frame types received by the device. Possible eBPF use cases could be: - implement new statistics through bpf maps - implement fast packet filtering (e.g in monitor mode) - ...
