Without it, XDP_ABORTED falls into the default case which logs a misleading "invalid XDP action" warning instead of tracing the abort via trace_xdp_exception(). Add the missing XDP_ABORTED case with trace_xdp_exception(), matching the handling already present in the skb path (cpu_map_bpf_prog_run_skb), devmap (dev_map_bpf_prog_run), and the generic XDP path (do_xdp_generic). Also pass xdpf->dev_rx instead of NULL to bpf_warn_invalid_xdp_action() in the default case, so the warning includes the actual device name. This aligns with the generic XDP path in net/core/dev.c which already passes the real device.
