Hi Florian

Both the Marvell10g and Aquantia PHY need the firmware in their FLASH.
It is a slow operation to perform. And so far, everybody has done it
from user space. I'm not sure we want to hold up the PHY driver probe
for multiple minutes if we where to do this in kernel.

The obvious second candidate is the Aquantia PHY. And i probably have
a board without firmware.
