The above is why nothing seems to work right. The kernel runtime
power management thinks there is no link on the port, and so is
putting the port into D3. We need to make sure that our driver wakes
the device to read link state (the problem is that wake from D3, plus
time to get link can take ~4 seconds).

but was the light blinking or solid? (link light) or was it just out.

> * At 26900: rmmod e1000e && modprobe e1000e: network still not working

it almost sounds like something in the docking station is not quite
waking successfully. If the device is in D3, the wake signal was
either missed by the system, or never asserted. If you unplug the
link and plug it back in, with the driver loaded and it reporting D3
(should go to PME+ and then D0 once cable is plugged in ) does it
help?
