From: Aashish Verma <redacted> netif_set_real_num_tx_queues() & netif_set_real_num_rx_queues() should be used to inform network stack about the real Tx & Rx queue (active) number in both stmmac_open() and stmmac_resume(), therefore, we move the code from stmmac_dvr_probe() to stmmac_hw_setup().

Nack. You need to hold rtnl lock when calling this and at suspend / resume you don't. --- Thanks, Jose Miguel Abreu _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
