Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>
Fix few instances of delayable work handlers using the k_work pointer
directly in a CONTAINER_OF pointing to a k_work_delayable.
This is harmless since the k_work is the first element in
k_work_delayable, but using k_work_delayable_from_work is the right way
of handling it.
Change a couple of explicit CONTAINER_OF doing the same work as the
macro in the process.

This fixes 3 issues that came within PR #59124 for ppp uart usage.
Earlier start/stop of ppp was done at enable() but that
was removed in PR #59124. Now putting enable/disable() back and
putting start/stop there.
Additionally, there was a double ppp carrier ON when NET_EVENT_IF_DOWN.
For that net_if_carrier_on/off is set in uart ppp.c driver.
Also, maybe worth to be mentioned that after PR #59124 there is no
ppp carrier off when lcp is disconnected, for workaround that change,
application should use ppp dead/running events.

Currently, if CONFIG_SLIP_TAP is enabled (default for QEMU), and no
other Ethernet driver is enabled, the following warning is printed by
CMake:
No SOURCES given to Zephyr library: drivers__ethernet
This happens because SLIP_TAP enabled Ethernet L2, but has no actual
sources in drivers/ethernet. This commit fixes this, by moving the
actual definition of the SLIP TAP Ethernet interface into a separate
file, within drivers/ethernet. Technically, in that configuration SLIP
defines a Ethernet device, implementing Ethernet API, so such a change
is justifiable, and prevents unwanted warning from being generated.

net_pkt_get_frag() and a few other functions did not specify the
allocated fragment length, incorrectly assuming that fixed-sized
buffers are always used.
In order to make the function work properly also with variable-sized
buffers, extend the function argument list with minimum expected
fragment length parameter. This allows to use net_buf_alloc_len()
allocator in variable buffer length configuration, as well as verify if
the fixed-sized buffer is large enough to satisfy the requirements
otherwise.
Update the existing codebase to provide the expected fragment length,

net_pkt_alloc_buffer() will use the maximum packet length of
NET_IPV4_MTU in case the interface MTU is smaller than this. Because of
this, the using the loopback interface with smaller MTU leads to
additional fragmentation at the TCP layer, which impacts performace and
requires more network buffers for tests to execute.

Fixes: #38403
Adding NET_DRIVERS menuconfig so that network drivers are grouped
together in its own menu entry under drivers, similar to most other
drivers.
This further has the advantages that `CONFIG_NET_DRIVERS` can be used
for testing to determine if network drivers has been selected.
This changed revealed a dependency loop where both `select` (for SLIP)
and `depends` (for PPP) which both depends on NET_DRIVERS` where in use
in the dependency tree for Qemu networking, especially NET_SLIP_TAP.
This is handled by defaulting `NET_DRIVERS` to `y` when building for a
Qemu target.
`SLIP` had a dependency to `!QEMU_TARGET || NET_QEMU_SLIP`. This is
changed so that SLIP prompt depends on `!QEMU_TARGET` which provides
full user control in hardware but makes the symbol promptless on Qemu
targets.

When PPP is muxed, using uart_poll_out resulted in each byte getting
wrapped in a muxing header. This led to UART bombardment which
can quickly cause some modems to hang and panic. This was observed
regularly using a SIMCOM7600E modem.
A perfect fix would involve rewriting ppp.c, uart_mux.c and
modem_iface_uart.c to all use another UART API, but that would be more
invasive by several orders of magnitude than this one, which utilizes
the fact that the uart_mux implementation of uart_fifo_fill does NOT
require ISR context. Since the Zephyr UART API states that the behavior
of uart_fifo_fill outside of ISR context is implementation defined, this
should be kosher.

This commit fixes the following issue:
When using slip without TAP, i.e. CONFIG_SLIP_TAP=n (default), while
another ethernet interface is enabled and sets CONFIG_NET_L2_ETHERNET=y.
This causes ethernet_init() to be wrongly called with struct dummy_api
instead of struct ethernet_api.
ethernet_init() expects struct ethernet_api (by cast), so we end up
with the get_capabilities field pointing to garbage!
Actually, as we are using the dummy api, we don't need to call
ethernet_init() at all.
Sole dependency on CONFIG_NET_L2_ETHERNET is wrong because it
can be enabled by another interface.
