The hardware has always in the past, still does, and probably always will work fine without a PHY driver. Link up/down are correctly handled.

No. Nothing would be gained.
All we are trying to do, is allow for loading of 1G PHY drivers via the -EPROBE_DEFER mechanism while continuing to allow the 10G and 40G ports to function without a PHY driver.
Specifically, we are *not* attempting to solve the problem of re-architecting the kernel phy_device infrastructure so that it would be possible to write a Cortina PHYs driver. Nor are we proposing that a Cortina PHY driver be written that would fit into the current infrastructure.
To this end, I still think the current patch takes the best approach.
Thanks, David Daney
