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
will then pass the good packets off to the network stack by calling
net_process_received_packet().

This value is not used by the network stack and is available in the
global data, so stop passing it around. For the one legacy function
that still expects it (init op on old Ethernet drivers) pass in the
global pointer version directly to avoid changing that interface.

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.

Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
fails, fall back to use dev->enetaddr, which could be filled up by
the ethernet device driver:
With the current code, introduced with below commit, eth_write_hwaddr()
will fail immediately if there is no eth<n>addr in the environment variables.
However, e.g. for an overo based product that uses the SMSC911x ethernet
chip (with the MAC address set via EEPROM connected to the SMSC911x chip),
the MAC address is still OK.
On mx28 boards that are depending on the OCOTP bits to set the MAC address
(like the Denx m28 board), the OCOTP bits should be used instead of
failing on the environment variables.
Actually, this was the original behavior, and was later changed by
commit 7616e78508.

Instead of counting the device index everytime a functions needs it, store
it in the eth_device struct. eth_register() keeps track of the indices and
updates the device's index number. This simplifies some functions in
net/eth.c.
Additionally, a network driver can now query its index, eg. to get the
correct environment ethaddr name.

Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).
This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)
We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.
We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,
we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.
