From: Markus Reichl <m.reichl@xxxxxxxxxxxxx> commit 0bf3885324a8599e3af4c7379b8d4f621c9bbffa upstream. On boards with LAN9514 and no preconfigured MAC address we don't get an ip address from DHCP after commit a049a30fc27c ("net: usb: Correct PHY handling of smsc95xx") anymore. Adding an explicit reset before starting the phy fixes the issue.
