9ba9e85f3f net: Fix NET_RANDOM_ETHADDR dependencies
NET_RANDOM_ETHADDR depends on lib/rand.c. This patch adds dependency to
Kconfig to ensure that library is also compiled.

Remove the definitions from Blackfin boards' include/configs.

6e0d26c050 net: Handle ethaddr changes as an env callback
When the ethaddr is changed in the env, update the device pdata at the
same time (only if it is probed for the DM case; only if registered for
the non-DM case). Again this gets us closer to completely non-polled
env needed to simplify the net_loop.

This requires that the NET feature select the REGEX feature.

fd3056337e net: Use env callbacks for net variables
Instead of checking for changes to the env each time we enter the
net_loop, use the env callbacks to update the values of the variables.
Don't update the variables when the source was programmatic, since the
variables were the source of the new value.

When the ethaddr changes in the env, the hardware should also be updated

3bc427006a dm: net: Use existing Ethernet init for driver model
At present even with driver model is used there is still much manual init
of related devices: PHY, environment and board init. Until these requirements
are dealt with in another way we need to keep them around.

Break out the init portion of the legacy eth_initialize() into a separate
function and call it from both the legacy and driver model eth_initialize()
functions.

implementation for eth it turns this into a completely useless case

(rotating through the eth adapters if ethrotate != no).

It also defaulted to retry forever. It is now changed to default to not
