Subject: [PATCH]drivers/net/phy/: default return value in ioctl phy.c

Hello Andy,

This patch (to 2.6.23.9) add a default return value EOPNOTSUPP to the ioctl 
function. The problem with the always 0 return value is that the iwconfig 
(wireless) tool found a valid device when an ethernet device uses the phy 
abstraction layer.
I 've tetsted this with the macb driver.
