[net-next,0/9] net: phy: icplus: cleanups and new features

Message

Cleanup the PHY drivers for IPplus devices and add PHY counters and MDIX
support for the IP101A/G.

Patch 5 adds a model detection based on the behavior of the PHY.
Unfortunately, the IP101A shares the PHY ID with the IP101G. But the latter
provides more features. Try to detect the newer model by accessing the page
selection register. If it is writeable, it is assumed, that it is a IP101G.

With this detection in place, we can now access registers >= 16 in a
correct way on the IP101G; that is by first selecting the correct page.
This might previouly worked, because no one ever set another active page
before booting linux.

The last two patches add the new features.
