Currently when booting dhcp_run() may be executed multiple times:
once in eth_bootdev_hunt() and once in the network booting bootmeth.
We need to call eth_bootdev_hunt() when setting up the EFI sub-system to
supply the simple network protocol. We don't need an IP address set up.
We can reduce the bootime by not executing dhcp_run() in
eth_bootdev_hunt().
Furthermore eth_bootdev_hunt() with autostart=yes leads on the legacy
network stack leads to downloading a file via TFTP and to booting the
downloaded file.
Instead of running dchp_run() just check that there is a network device
in eth_bootdev_hunt().

When a successful neighbor advertisement is received, the ethernet
address should be saved for later use to avoid having to redo the
neighbor discovery process.
For example, with TFTP the address should get saved into
"net_server_ethaddr". This is being done correctly with ARP for IPv4,
but not for neighbor discovery with IPv6.

We have a some boards that rarely starts networking abnormally, so there are
many timeouts during file transfer. In the same time there is a normal transfer
between timeouts. In this case we can continue transfer (instead of connection
aborting) by just clearing timeout counter on every successful block.
This patch does not affect the case when several timeouts happen one after
another. The transfer will be aborted. Thus the transfer will be
continued in the case of unstable link, but will be aborted in the case
of inaccessible server.
Feature downside: it may greatly slowdown (instead of abort) file transfer
in the case of unstable link.

Changes:
* Fix initial send sequence always zero issue
* Use state machine close to RFC 9293. This should make TCP
transfers more reliable (now we can upload a huge array
of data from the board to external server)
* Improve TCP framework a lot. This should make tcp client
code much more simple.
* rewrite wget with new tcp stack
* rewrite fastboot_tcp with new tcp stack
It's quite hard to fix the initial send sequence (ISS) issue
with the separate patch. A naive attempt to fix an issue
inside the tcp_set_tcp_header() function will break tcp packet
retransmit logic in wget and other clients.
Example:
Wget stores tcp_seq_num value before tcp_set_tcp_header() will
be called and (on failure) retransmit the packet with the stored
tcp_seq_num value. Thus:
* the same ISS must allways be used (current case)
* or tcp clients needs to generate a proper ISS when
required.
A proper ISS fix will require a big redesing comparable with
a this one.

Commit 356011f7ac ("lwip: fix code style issues") has inadvertently
broken the support for the legacy syntax:

invalid uri, no file path
Invalid URL. Use http(s)://
The reason is two calls to strncpy() were replaced by strlcpy() without
paying attention to the fact that they are not equivalent in the present
case. Since we are using a character counter (n) and since we do not
depend on having a properly null-terminated string at each step in the
parsing, strlcpy() is not justified and strncpy() is the right tool for
the job. So use it again.

Set the device path of the efi boot device to an HTTP device path
(as formed by efi_dp_from_http) when the next boot stage is loaded
using wget (i.e., when wget is used with wget_info.set_bootdev=1).
When loaded from HTTP, the device path should account for it so that

new device. This incorrect behavior was detected thanks to the eth_rotate
sandbox test (dm_test_eth_rotate()).
Fix it by re-using a sequence similar to what NET has in net_loop().

Move the initialization of the ethernet devices out of the new_netif()
function. Indeed, new_netif() accepts a struct device argument, which
is expected to be valid and active. The activation and selection of
this device are achieved by eth_init() (on first time the network
stack is used) and eth_set_current(). This is what takes care of the
ethrotate and ethact environment variables. Therefore, move these calls
to a new function: net_lwip_set_current(), and use it whenever a
net-lwip command is run.
This patch hopefully fixes the incorrect net-lwip behavior observed on
boards with multiple ethernet interfaces [1].
Tested on an i.MX8MPlus EVK equipped wih two ethernet ports. The dhcp
command succeeds whether the cable is plugged into the first or second
port.
