A number of network related files were imported from the LiMon
project; these contain a somewhat unclear license statement:
Copyright 1994 - 2000 Neil Russell.
(See License)
I analyzed the source code of LiMon v1.4.2 which was used for this
import. It does not contain any "License" file, but the top level
directory contains a file "COPYING", which turns out to be GPL v2
of June 1991. So it is legitimate to conclude that the LiMon derived
files are also to be released under GPLv2. Mark them as such.

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.

This fixes the following compiler warnings when activating
CONFIG_MCAST_TFTP:
tsec.c: In function 'tsec_mcast_addr':
tsec.c:130:2: warning: passing argument 2 of 'ether_crc' makes pointer
from integer without a cast [enabled by default]
In file included from /work/u-boot-net/include/common.h:874:0,
from tsec.c:15:
/work/u-boot-net/include/net.h:189:5: note: expected 'const unsigned
char *' but argument is of type 'u8'
tsec.c: In function 'tsec_initialize':
tsec.c:646:13: warning: assignment from incompatible pointer type

eth.c: In function 'eth_mcast_join':
eth.c:358:2: warning: passing argument 2 of 'eth_current->mcast' makes
integer from pointer without a cast [enabled by default]
eth.c:358:2: note: expected 'u32' but argument is of type 'u8 *'
In the eth_mcast_join() implementation, eth_current->mcast()
takes a u8 pointer to the multicast mac address and not a ip
address value as implied by its prototype.
Fix parameter type mismatch for tsec_macst_addr() (tsec.c):
ether_crc() takes a u8 pointer not a u8 value.
mcast() is given a u8 pointer to the multicats mac address.
Update parameter type for the rest of mcast() instances.

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.

A few subsystems are using the same define "NAMESIZE". This has been
working so far because they define it to the same number. However, I
want to change the size of eth_device's NAMESIZE, so rather than tweak
the define names, simply drop references to it. Almost no one does,
and the handful that do can easily be changed to a sizeof().

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.

When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

This is long over due. All but two net drivers have been converted, but

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.
