With commit be9dad1f9f26604fb ("net: phy: suspend phydev when going to HALTED"), the PHY device will be put in a low-power mode using BMCR_PDOWN if the the interface is set down. The smsc911x driver does a software_reset opening the device driver (ndo_open). In such case, the PHY must be powered-up before access to any register and before calling the software_reset function. Otherwise, as the PHY is powered down the software reset fails and the interface can not be enabled again. This patch fixes this scenario that is easy to reproduce setting down the network interface and setting up again. $ ifconfig eth0 down $ ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error Signed-off-by: Enric Balletbo i Serra <eballetbo@iseebcn.com> Signed-off-by: David S.
