512be89796 net: introduce CONFIG_DNS
Introduce the DNS Kconfig symbol so that various network commands may
use host names without the dns command (CMD_DNS) being selected.

a383869d6b net: lwip: move dns init to common function
move the dns init including setting the dns servers from env vars to a
common function as other commands that support hostname lookups will
need this.

08a8d1455a net: lwip: call sys_check_timeouts and schedule on rx
Call schedule() in net_lwip_rx() to service U-Boot tasks and
actions during packet rx.

As a cleanup also move sys_check_timeouts() here and remove it from the
functions that call net_lwip_rx().

This resolves the issue of an active watchdog resetting the board on
long network activities.

ae9ff5ae6f global: Avoid indirect inclusion of <env.h> from <net.h>
Now that env_get_ip() has been removed, the include file <net.h> does
not need anything from <env.h>. Furthermore, include/env.h itself
includes other headers which can lead to longer indirect inclusion
paths. To prepare to remove <env.h> from <net.h> fix all of the
remaining places which had relied on this indirect inclusion to instead
include <env.h> directly.

5666865dec net: lwip: fix initialization sequence before a command
The things that are done prior to executing a network command with
NET_LWIP are not consistent with what is done with NET. It impacts the
selection of the current device, and more precisely if the active device
is invalid NET would return an error while NET_LWIP would try to pick a
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().
This piece of code is inserted in a function called net_lwip_eth_start()
renamed from net_lwip_eth_set_current().

9f6b9f57fe net: lwip: move eth_init() out of new_netif()
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.
