I can see the wm2, wm3 interfaces but their status is always inactive.

------------------------------------------------------------

>How-To-Repeat:
Use a machine with wm cards(PCI-X) with a fiber phy.
And try to enable the NiC using ifconfig wm2 up

The status never changes to active.

>Fix:
Sorry.
