99e139d590 net: use common rand()/srand() functions
Replace rand() with the functions from lib/. The link-local network code
stores its own seed, derived from the MAC address. Thus making it
independent from calls to srand() in other modules.

4ef8d53caa net: Allow filtering on debug traces in the net subsystem
Add several levels of DEBUG prints so that you can limit the noise to
the severety of your problem.

DEBUG_LL_STATE = Link local state machine changes
DEBUG_DEV_PKT = Packets or info directed to the device
DEBUG_NET_PKT = Packets on info on the network at large
DEBUG_INT_STATE = Internal network state changes

c697576262 net: Work-around for brain-damaged Cisco equipment with arp-proxy
Cisco's arp-proxy feature fails to ignore the link-local address range
This means that a link-local device on a network with this Cisco
equipment will reply to ARP requests for our device (in addition to
our reply).
If we happen to reply first, the requester's ARP table will be
populated with our MAC address, and one packet will be sent to us...
shortly following this, the requester will get an ARP reply from the
Cisco equipment telling the requester to send packets their way
instead of to our device from now on.
This work-around detects this link-local condition and will delay
replying to the ARP request for 5ms so that the first packet is sent
to the Cisco equipment and all following packets are sent to our
device.

6937664426 net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back
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.

what is now net_auto_load() instead.

This also fixes an incorrect call to TftpStart() which was never seen
since apparently no boards enable rarp.

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.

5f184715ec Create PHY Lib for U-Boot
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.

Pulled ethtool.h and mdio.h from:
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

8ad25bf8d9 Net: clarify board/cpu_eth_init calls
This has always been confusing, and the idea of these functions returning the

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.

c96f86eefc TFTP: allow for adjustable retransmission timout
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.

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

aabb8cb081 nfs: NfsTimeout() updates
- 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.

 - if receives the file size, a single line (50 chars) are printed.

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).

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.

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.

6a86bb6c25 net: Fix TftpStart() ip:filename bug
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:

=> tftp 0x100000 10.52.0.62:/home/ptyser/non_existant
Speed: 100, half duplex
Using eTSEC1 device
TFTP from server 10.52.0.62; our IP address is 10.52.253.79
                 ^^^^^^^^^^ CORRECT
Filename '/home/ptyser/non_existant'.
          ^^^^^^^^^^^^^^^^^^^^^^^^^ CORRECT
Load address: 0x100000
Loading: *
TFTP error: 'File not found' (1)

eTSEC2: No link.
Speed: 100, half duplex
Using eTSEC1 device
TFTP from server 10.52.0.33; our IP address is 10.52.253.79
                 ^^^^^^^^^^ WRONG
Filename '10.52.0.62'.
          ^^^^^^^^^^ WRONG
Load address: 0x100000
Loading: *
TFTP error: 'File not found' (1)

TftpStart() was modified to not modify the 'BootFile' string.

e83cc06375 net: Make TFTP server timeout configurable
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.

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

"%d" and incorrect arguments.  Others were just annoying, like
int-long mismatches on a system where both are 32 bits.  It's worth

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

now before checking the checksum.

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.

c2b7da5522 SPARC/LEON3: Added GRETH Ethernet 10/100/1000 driver.
GRETH is an Ethernet 10/100 or 10/100/1000 MAC with out without
a debug link (EDCL). The GRETH core is documented in GRIP.pdf
available at www.gaisler.com.

If the GRETH has GigaBit support (GBIT, Scatter gather, checksum
offloading etc.) can be determined by a bit in the control register.
The GBIT MAC is supported by operating in GRTEH 10/100 legacy mode.

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).
