TFTP'ing a file of size 1747851 bytes with CONFIG_IP_DEFRAG and
CONFIG_TFTP_BLOCKSIZE set to 4096 fails with a timeout, because
the last fragment is not taken into account. This patch fixes
IP fragments having less than 8 bytes of payload.

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.

For some reason, (which I can't find any documentation on), if U-Boot
gives a port number higher than 17500 to a Microsoft DNS server, the
server will reply to port 17500, and U-Boot will ignore things (since
that isn't the port it asked the DNS server to reply to).

This fixes that by ensuring the random port number is less than 17500.

So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

There are boards out there that do not have network support in
U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This
makes it desirable to be able to port network configuration (like
the IP address) to the Linux kernel.

We should not make the passing of the IP configuration to Linux
dependent on U-Boot features / settings.

For this, make getenv_IPaddr() global. This fixes build error

u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr'

on various architectures.

- NfsTimeout() does not correctly update the NFS timeout value which
  results in NfsTimeout() only being called once in certain situations.
  This can result in the 'nfs' command hanging indefinetly.  For
  example, the command:

    nfs 192.168.0.1:/home/user/file

  will not exit until ctrl-c is pressed if 192.168.0.1 does not have an
  NFS server running.

  This issue is resolved by reinitializting the NFS timeout value inside
  NfsTimeout() when a timeout occurs.

- Make the 'nfs' command print the 'T' character when a timeout occurs.
  Previously there was no indication that timeouts were occuring.

- Mimic the 'tftpboot' command and when a download fails print "Retry
  count exceeded; starting again", and restart the download taking the
  'netretry' environment variable into account.

Optionally add RFC 2349 "Transfer Size Option", so we can minimize the
time spent sending data over the UART (now print a single line during a
tftp transfer).

 - If turned on (CONFIG_TFTP_TSIZE), U-Boot asks for the size of the file.
 - if receives the file size, a single line (50 chars) are printed.
     one hash mark == 2% of the file downloaded.
 - if it doesn't receive the file size (the server doesn't support RFC
     2349, prints standard hash marks (one mark for each UDP frame).

Increasing the block size is useful if CONFIG_IP_DEFRAG is

The defragmenting code is enabled by CONFIG_IP_DEFRAG; the code is
useful for TFTP and NFS transfers.  The user can specify the maximum
defragmented payload as CONFIG_NET_MAXDEFRAG (default 16k).
Since NFS has a bigger per-packet overhead than TFTP, the static
reassembly buffer can hold CONFIG_NET_MAXDEFRAG + the NFS overhead.

The packet buffer is used as an array of "hole" structures, acting as
a double-linked list. Each new fragment can split a hole in two,
reduce a hole or fill a hole. No support is there for a fragment
overlapping two diffrent holes (i.e., thre new fragment is across an
already-received fragment).

In the previous enetaddr refactoring, the assumption with commit 56b555a6
was that the eth layer would handle the env -> device enetaddr syncing.
This was not the case as eth_initialize() is called only once and the sync
occurs there.  So make sure the eth_init() function does the env -> device
sync with every network init.

Linux's netconsole works much better when you can pass it the MAC address of
the server. (otherwise it just uses broadcast, which everyone else on my
network complains about :)

This sets the env var "serveraddr" (to match ethaddr), so that you can pass
it to linux with whatever bootargs you want to....

Here it is again - slightly modified & smaller:
  - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0)
  - README.dns is added
  - syntax is changed (now takes a third option, the env var to store
    the result in)
  - add a random port() function in net.c
  - sort Makefile in ./net/Makefile
  - dns just returns unless a env var is given
  - run through checkpatch, and clean up style issues
  - remove packet from stack
  - cleaned up some comments
  - failure returns much faster (if server responds, don't wait for
    timeout)
  - use built in functions (memcpy) rather than byte copy.

The patch fixes the bug of partial initialization of global network
parameters.

Upon u-boot's start up the first ping command causes a failure of the
consequent TFTP command. It happens in the recently added mechanism of
the NetLoop initialization where initialization of global network
parameters is separated in the NetInitLoop routine which is called per
env_id change. Thus, ping request will initialize the network parameters
necessary for ping operation only, afterwards the env_changed_id will be
set to the env_id that will prevent all following initialization requests
from other protocols.
The problem is that the initialized by ping subset of network parameters
is not sufficient for other protocols and particularly for TFTP which
requires the NetServerIp also.
