This patch set is to add support for user to get or set Tx/Rx channel

Tested on Intel Tigerlake Platform.

netif_set_real_num_tx_queues() & netif_set_real_num_rx_queues() should be

in both stmmac_open() and stmmac_resume(), therefore, we move the code
from stmmac_dvr_probe() to stmmac_hw_setup().
