Comment 7 for bug 673504

SRU Justification:

Impact: The smsc95xx driver generates a new random MAC address on every
ifdown/up instead of only one during driver's init, and doesn't let the user to
set up the mac address using known methods like ifconfig usb0 hw ether <mac>.

Fix: Just move the init_mac_address function to bind instead of reset.

Testcase: The interface should keep the same generated mac address even when
giving ifdown/up, and the user should be able to set up the mac address using
'ifconfig usb0 hw ether <mac>.

Patch is already upstream as f4e8ab7, and is tested already with a compiled
kernel deb with the fix included.
