Subject: C45 Phys and PHY_FORCING state

Hello Andrew and Florian,

Currently I have a 10G C45 phy that is fixed at 10G link. This
version does not support auto negotiation so I'm turning off the
feature in phydev struct field. I found out that when I do this
phylib is not composing C45 frames and is instead using C22. This
is due to call to genphy_udpate_link() which doesn't work on my
phy because it doesn't support C22.

If I apply attached patch then things work perfectly fine. Can
you please review it ?

Thanks and Best Regards,
Jose Miguel Abreu
