ea45cb0adc net: Make sure IPaddr_t is 32 bits in size
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.

23a70bf9c3 net/net.c: Update ipaddr if the environment has changed
At least on ARM the ipaddr is only set in board_init_r function. The
problem is if ipaddr is not defined in environment importing another
environment defined don't update the ipaddr value.

For example, suppose we've a default environment without net variables
defined and we want to import an uEnv.txt environment from SD-card like
this:

  ipaddr=192.168.2.240
  netmask=255.255.255.0
  gatewayip=192.168.2.1
  serverip=192.168.2.114

Then if you try boot from NFS results in:

  Importing environment from mmc ...
  Running uenvcmd ...
  smc911x: detected LAN9221 controller
  smc911x: phy initialized
  smc911x: MAC ac🇩🇪48:00:00:00
  *** ERROR: `ipaddr' not set

The ipaddr at this point is NULL beacause is only set at board_init_r
function. This patch updates the ipaddr value if the environment has
changed.

9739946cc5 ./net/net.c - make Microsoft dns servers happy with random_port() numbers
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.

6a45e38495 Make getenv_IPaddr() global
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

5cfaa4e54d net: defragment IP packets
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).

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.

3c172c4fdb NetLoop initialization bug
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.

2f70c49e5b netloop: speed up NetLoop
NetLoop polls every cycle with getenv some environment variables.
This is horribly slow, especially when the environment is big.

This patch reads only the environment variables in NetLoop,
when they were changed.

Also moved the init part of the NetLoop function in a seperate
function.

af8626e0c0 Fix IP alignment problem
This patch removes volatile from:
volatile IP_t *ip = (IP_t *)xip;

Due to a bug, avr32-gcc will assume that ip is aligned on a word boundary when
using volatile, which causes an exception since xip isn't aligned on a word
boundary.

49f3bdbba8 net: express the first argument to NetSetTimeout() in milliseconds
Enforce millisecond semantics of the first argument to NetSetTimeout() --
the change is transparent for well-behaving boards (CFG_HZ == 1000 and
get_timer() countiing in milliseconds).

Rationale for this patch is to enable millisecond granularity for
network-related timeouts, which is needed for the upcoming automatic
software update feature.

Summary of changes:
- do not scale the first argument to NetSetTimeout() by CFG_HZ
- change timeout values used in the networking code to milliseconds

6b52cfe16c Get rid of annoying/superfluous bad-checksum warning message
U-boot can complain a lot about 'checksum bad' when it is attached to the network.
It is annoying for ordinary users who start to doubt the network connection
in general when they see messages like this.

This is caused by the routine NetCksumOk() which cannot handle IP-headers longer
than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them
now before checking the checksum.

40cb90ee2b net: make ARP timeout configurable
Currently the timeout waiting for an ARP reply is hard set to 5 seconds.
On i.MX31ADS due to a hardware "strangeness" up to four first IP packets
to the boards get lost, which typically are ARP replies. By configuring
the timeout to a lower value we significantly improve the first network
transfer time on this board. The timeout is specified in milliseconds,
later internally it is converted to deciseconds, because it has to be
converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on
different boards.

f85b607105 Introduce new eth_receive routine
The purpose of this routine is receiving a single network frame, outside of
U-Boot's NetLoop(). Exporting it to standalone programs that run on top of
U-Boot will let them utilise networking facilities. For sending a raw frame
the already existing eth_send() can be used.

The direct consumer of this routine is the newly introduced API layer for
external applications (enabled with CONFIG_API).

Add ICMP_ECHO_REQUEST packet support by responding with a ICMP_ECHO_REPLY.

This permits the ping command to test the phy interface when the phy
is put in loopback mode (typically by setting register 0 bit 14).

It also allows the port to respond to an external ping when u-boot is
processing some other net command (such as tftp).  This is useful when
tftp appears to hang.
