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.

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

Here it is again - slightly modified & smaller:

- README.dns is added
- syntax is changed (now takes a third option, the env var to store

- 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.

The TftpStart() function modifies the 'BootFile'
string when 'BootFile' contains both an IP address
and filename (eg 1.2.3.4:/path/file). This causes
subsequent calls to TftpStart to incorrectly parse
the TFTP filename and server IP address to use.
For example:

There are two aspects of a TFTP transfer involving timeouts:
1. timeout waiting for initial server reply after sending RRQ
2. timeouts while transferring actual data from the server
Since the upcoming auto-update feature attempts a TFTP download during each
boot, it is undesirable to have a long delay when the TFTP server is not
available. Thus, this commit makes the server timeout (1.) configurable by two
global variables:
TftpRRQTimeoutMSecs
TftpRRQTimeoutCountMax
TftpRRQTimeoutMSecs overrides default timeout when trying to connect to a TFTP
server, TftpRRQTimeoutCountMax overrides default number of connection retries.
The total delay when trying to download a file from a non-existing TFTP server
is TftpRRQTimeoutMSecs x TftpRRQTimeoutCountMax milliseconds.
Timeouts during file transfers (2.) are unaffected.
