5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
[ Upstream commit 6f32c086602050fc11157adeafaa1c1eb393f0af ]
ravb_phy_start() may fail. If that happens, the TX queues will remain
started. Thus, move the netif_tx_start_all_queues() after PHY is
successfully initialized.
Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper")
