Subject: [PATCH net 2/7] net: stmmac: Fix incorrect location to set real_num_rx|tx_queues
Date:   Tue, 14 Jan 2020 10:01:11 +0800
Message-Id: <1578967276-55956-3-git-send-email-boon.leong.ong@intel.com>
In-Reply-To: <1578967276-55956-1-git-send-email-boon.leong.ong@intel.com>

Precedence: bulk

From: Aashish Verma <aashishx.verma@intel.com>

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")
