[PATCH 5.8 220/633] net: stmmac: Fix incorrect location to set real_num_rx|tx_queues

From: Greg Kroah-Hartman
Date: Tue Oct 27 2020 - 11:02:01 EST


From: Aashish Verma <aashishx.verma@xxxxxxxxx>

[ Upstream commit 686cff3d7022ddf35d7e38bc80191eb92de5989a ]

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().

Fixes: c02b7a914551 net: stmmac: use netif_set_real_num_{rx,tx}_queues
