doc/README.drivers.eth seems like a good source for understanding
U-Boot's network subsystem, but is only talking about legacy network
drivers. This is particularly sad as proper documentation would help in
porting drivers over to the driver model.
Rewrite the document to describe network drivers in the new driver model
world. Most driver callbacks/methods are almost identical in their
semantic, but recv() differs in some important details.
Also keep some parts of the original text at the end, to help
understanding old drivers. Add some hints on how to port drivers over.
This also uses the opportunity to reformat the document in reST, on the
way moving it into doc/driver-model and adding it into the structure
there.

Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.
This cleans up the temporary hacks that were added to this interface
along with the DM support.
This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).

README.drivers.eth still refers to the deprecated miiphy_register().
Update the doc to mention new APIs mdio_alloc() and mdio_register().

Add a new function to the eth_device struct for programming a network
controller's hardware address.
After all network devices have been initialized and the proper MAC address
for each has been determined, make a device driver call to program the
address into the device. Only device instances with valid unicast addresses
will be programmed.

The dev->halt() func can be called at any time, and the dev->recv() func
does not need to use NetRxPackets[] when calling NetReceive().

As discussed on mailing list, <0 indicates failure, >=0 indicates number
of interfaces found.
Also added blurb about private data
