El seguimiento de envío xmit ocurre después de completar metadata_map. Simplemente reordenar las funciones mlx5e_ptp_metadata_map_put y mlx5e_ptpsq_track_metadata en el contexto mlx5e_txwqe_complete no es lo suficientemente bueno ya que ambas el compilador y la CPU son libres de reordenar estas dos funciones. Si se produce un reordenamiento, se verá el problema que supuestamente fue solucionado por 7e3f3ba97e6c (\"net/mlx5e: Seguimiento del envío de xmit a PTP WQ después de completar el mapa de metadatos\").
