Hi Richard
Forward declarations are considered bad. Please add a new patch to the
series which moves code around first. You can probably move
dp83640_probe() further down.

David will probably complain about reverse christmas tree. Having to
fold dp83640_private is unfortunate here. Maybe consider adding a
macro for the container_of() so you can avoid the fold?

FYI:
When using phylink, not phylib, this call will not happen. You need to
add a similar bit of code in phylink_mac_config().
For the moment what you have is sufficient. I doubt anybody is using
the dp83640 with phylink, and the new hardware you are targeting seems
to be RGMII based, not SERDES, which is the main use case for PHYLINK.
