I'm sorry, I made a mistake. The real_num_rx_queues field, with the 3.10 kernel which is currently being used with the OpenWRT trunk branch, is only defined when CONFIG_RPS flag is active. CONFIG_RPS is only active when CONFIG_SMP is active.
This as changed (beyond 3.13 version) and the real_num_rx_queues field depends now on CONFIG_SYSFS field.
