On a platform with a serial console this can result in excessively long boot times in a way that looks like an infinite loop when multiple busses are present. Since 0f183fd151c (net/fsl: enable extended scanning in xgmac_mdio) we perform more scanning so there are potentially more failures. Reduce the logging level to dev_dbg which is consistent with the Freescale enetc driver. Cc: Jeremy Linton Signed-off-by: Jamie Iles Reviewed-by: Andrew Lunn Signed-off-by: David S.
