Robert Lubos 666e9f80d6 net: ipv6: Remove in6_addr from packed net_ipv6_hdr struct
Replace unpacked in6_addr structures with raw buffers in net_ipv6_hdr
struct, to prevent compiler warnings about unaligned access.

Remove __packed parameter from `struct net_6lo_context` since the
structure isn't really serialized.

Torsten Rasmussen 8e64038559 drivers: net: adding NET_DRIVERS menuconfig
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.

Marcin Niestroj d08c6ee113 drivers: net: ppp: fix removing CRC16 from packet
CRC16 was removed by simply decreasing length of the last fragment by 2.
This worked as long as last fragment was longer than 1 byte. If not,
then last fragment was corrupted (its length ended up being 65535),
leading to undefined behavior.

Fix CRC16 removal by utilizing recently introduced
net_pkt_remove_tail(), that properly handles multiple fragments.

Benjamin Lindqvist 449fc7bb1c net: ppp: Avoid wrapping each byte in muxing headers
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.

Benjamin Lindqvist 54cb2bcd41 drivers: modem: gsm_ppp: Enable start/stop
These changes enable applications to restart the networking stack which
was previously not possible without rebooting the device. This was a
major show-stopper because it made power management impossible, and
furthermore made it impossible to recover from a bad modem state without
rebooting.

This has been verified to work on a SIMCOM7600E modem, both with and
without CONFIG_GSM_MUX enabled.

David Komel 92499fc9d1 drivers: net: slip: Allow slip to co-exist with other interfaces
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.

Marcin Niestroj 67f106820b net: ppp: consume ringbuf until it is empty
ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever, or simply to
the next timeout in PPP stack when data traffic continues.

Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.
