In many parts of the computing world having a unique MAC address
sitting in some on-NIC storage is considered the normal case.
Remove the warning to not scare the user unnecessarily.
This applies to Highbank/Midway and ARM's Juno, for instance.
Besides that this fixes the formatting on Midway, for instance,
which currently looks like:
...
Net: xgmac0
Warning: xgmac0 using MAC address from net device
, xgmac1

eth_get_dev() can return NULL which means device_probe() fails for
that ethernet device. Add return value check in various places or
U-Boot will crash due to NULL pointer access.

platdata->enetaddr was assigned to a value in dev_probe() last time.
If we don't clear it, for dev_probe() at the second time, dm eth
will end up treating it as a MAC address from ROM no matter where it
came from originally (maybe env, ROM, or even random). Fix this by
clearing platdata->enetaddr when removing an Ethernet device.

The previous eth_device struct returned by eth_get_dev() allowed
code to directly query the state member field. However, with
CONFIG_DM_ETH this data gets encapsulated (i.e. private), and
eth_get_dev() returns a udevice struct 'abstraction' instead.
This breaks legacy code relying on the former behaviour - e.g.
netconsole.
(see http://lists.denx.de/pipermail/u-boot/2015-June/216528.html)
The patch introduces a method to retrieve the ethernet device
state in a 'clean' and uniform way, supporting both legacy code
and driver model. The new function eth_is_active() accepts a
device struct pointer and tests it for ETH_STATE_ACTIVE.

Some drivers may want to implement this method for some of their devices but
not for others. So it is not possible to just leave the operation out of
the table. Drivers could get around this by masquerading as two separate
drivers but that seems unpleasant.
Allow the driver to return an error when it does not want to process the
write_hwaddr() method.

Some devices can take a long time to work out whether they have a new packet
or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do
this, since it waits until it gets a new packet on the wire before allowing
the USB bulk read packet to be submitted.
At present with driver mode the Ethernet receive code reads 32 packets. This
can take a very long time if we must wait for all 32 packets. The old code
(before driver model) worked by reading a single set of packets from the USB
device, then processing all the packets with in. It would be nice to use
the same behaviour with driver model.
Add a flag to the receive method which indicates that the driver should try
to find a packet if available, by consulting the hardware. When the flag is
not set, it should just return any packet data it has already received. If
there is none, it should return -EAGAIN so that the loop will terminate.

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.

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

Also remove the manual calls to set the hwaddr that was included in a

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.

Take a pass at plumbing errors through to the users of the network stack
Currently only the start() function errors will be returned from
NetLoop(). recv() tends not to have errors, so that is likely not worth
adding. send() certainly can return errors, but this patch does not
attempt to plumb them yet. halt() is not expected to error.

Stop forcing drivers to call net_process_received_packet() - formerly
called NetReceive(). Now the uclass will handle calling the driver for
each packet until the driver errors or has nothing to return. The uclass

net_process_received_packet().

Some functions in include/net.h are ported from
include/linux/etherdevice.h of Linux Kernel.
For ex.
is_zero_ether_addr()
is_multicast_ether_addr()
is_broadcast_ether_addr()
is_valid_ether_addr();
So, we should use the same function name as that of Linux Kernel,
eth_rand_addr(), for consistency.
Besides, eth_rand_addr() has been implemented as an inline function.
So it should not be surrounded by #ifdef CONFIG_RANDOM_MACADDR.

In "common/Makefile" "miiphyutil.o" gets built if any of the following
items enabled:
* CONFIG_PHYLIB
* CONFIG_MII
* CONFIG_CMD_MII
So it's possible to not define CONFIG_MII or CONFIG_CMD_MII and still
use functions like "miiphy_get_dev_by_name".
In its turn "miiphy_get_dev_by_name" traverses "mii_devs" list which is
not initialized because "miiphy_init" never got called.

Previously u-boot would initialize the network interface for every
network operation and then shut it down again. This makes sense for
most operations where the network in not known to be needed soon after
the operation is complete. In the case of netconsole, it will use the
network for every interaction with the shell or every printf. This
means that the network is being reinitialized very often. On many
devices, this intialization is very slow.
This patch checks for consecutive netconsole actions and leaves the
ethernet hardware initialized between them. It will still behave the
same old way for all other network operations and any time another
network operation happens between netconsole operations.

If the requested length is too small to hold the received packet,
eth_receive() will return -1 and will leave the packet in the receive
buffers. Instead of returning an error in this case, we return the first
portion of the received packet and remove it from the receive buffers.
This fixes FreeBSD's ubldr. Without this patch it will just stop receiving
packets if the NIC receives more than PKTBUFSRX too large packets.
