[PATCH 5.10 27/30] net: usb: Correct reset handling of smsc95xx

[Greg Kroah-Hartman]

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.
