e4a3d57dc7 net: Export auto_load, use it in rarp
The rarp code includes another instance of the auto_load logic, so call
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.

39bccd21d0 net: Hide more code behind CONFIG_CMD_TFTPPUT
This commit reduces code size a little by making the ICMP handler only
available to tftpput. This is reasonable since it is the only user at
present (ping just uses the normal handler).

4793ee6522 net: tftpput: Add support for receiving ICMP packets
ICMP packets can tell you when there is no server at the other end. It
is useful for tftp to figure this out, so that a quick error can be
displayed, rather than pointlessly retrying.

This adds an ICMP packet handler to the net interface.

6dc809f407 net/dns.c: Fix endian conversion for big-endian in dns command
net/dns.c used endian conversion macros wrongly (shorts in reply
were put swapped into CPU, and then ntohs() was used to swap it
back, which broke on big-endian).

Fix this by using the correct linux conversion macro for reading
a unaligned short in network byte order: get_unaligned_be16()
Thanks to Mike Frysinger pointing at the best macro to use.

Tested on big and little endian qemu boards (mips and versatile)

7616e78508 Add Ethernet hardware MAC address framework to usbnet
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.

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.
