[PATCH net 0/4] net: set 'mac_managed_pm' at probe time

[Wolfram Sang]

When suspending/resuming an interface which was not up, we saw mdiobus
related PM handling despite 'mac_managed_pm' being set for RAVB/SH_ETH.
Heiner kindly suggested the fix to set this flag at probe time, not at
init/open time. I implemented his suggestion and it works fine on these
two Renesas drivers. These are patches 1+2.

I then looked which other drivers could be affected by the same problem.
I could only identify two where I am quite sure. Because I don't have
any HW, I opted to at least add a FIXME and send this out as patches
3+4. Ideally, they will never need to go upstream because the relevant
people will see their patch and do something like I did for patches 1+2.

Looking forward to comments. Thanks and happy hacking!
