Some of these are from 'source'ing a file within a menu that has a
'depends on NET_L2_ETHERNET' (in drivers/ethernet/Kconfig) and then
adding another 'depends on NET_L2_ETHERNET' within it.
Similarly, subsys/net/l2/ethernet/Kconfig sources files within an
'if NET_L2_ETHERNET'.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

The ring_buf implementation is basically used as an array of net_buf
pointers in the RX path. The tail and head indexes are taken from the
RX descriptors and not from the ring_buf. That's why for example the
fact that head is never initialized doesn't cause problem. Only len is
used in free_rx_bufs(), but anyway this function is plainly broken as
it always free the first net_buf and doesn't set it back to NULL.

Scale down the TX path of the GMAC driver by waiting for a packet to be
fully sent before returning from the send function. This has a small
performance impact, but has a few advantages:
- It allows the Ethernet code to modify the packet afterward, fixing PTP
support on this board (see PR #12563).
- It returns an error to the IP stack in case of a transmit failure.
- It doesn't require net_buf to be thread safe.

to 1.

The SAM GMAC Ethernet driver currently keeps a reference to the packet

The SAM GMAC Ethernet driver uses scatter gather DMA to transmit data.
Each fragment of a network packet is mapped from a set of descriptors
that is used by the controller to do the DMA transfer. This means that
the packet is not necessary sent when the send() function returns. For
that reason the driver calls net_pkt_ref() on the packet to prevent it
from being freed. It is then unreferenced with net_pkt_unref() in the
TX ISR when the packet has effectively been sent.
However this doesn't work if the packet is modified in the meantime,
like it will be done in PR #12563 to remove the Ethernet header
contained in the first fragment. To avoid that, call net_pkt_frag_ref()
on each fragment of the packet, and unreferenced them with
net_pkt_frag_unref() in the TX ISR when the packet has effectively been
sent.

Atmel SAM Ethernet module is using a scatter-gather technique to
exchange data with the Ethernet driver. To communicate the location
of the data buffers the driver sets-up a so called descriptor list. This
is effectively a place in RAM containing a sequence of 32-bit words
representing buffer location and its status.
Currently the cache coherency is handled using cache clean or
invalidate. Unfortunately this strategy only works correctly when the
corresponding data size is a multiple of the cache line. This is not
the case here and might lead to data loss or corruption.
Instead of using cache operations, this patch moves the descriptor
listed to the recently added non-cached memory region, as recommended by
ATMEL. A data synchronisation barrier is still required for writes, as
the non-cached memory is defined with TEX=1, i.e. it is not strongly
ordered. The descriptor lists alignment can be decreased to 4 bytes, as
required by the SAM Ethernet module.
The RX/TX buffer are left unchanged, still managed by cache operations.

The SAM E70 GMAC ethernet driver reference a packet with net_pkt_ref()
when queueing a packet, and unreference it with net_pkt_unref() in the
ISR when it has been fully sent.
The call to net_pkt_ref() is done just after re-enabling the
interruptions, so there is however a small race condition that might
cause the packet to be unreference before being referenced. This is
only theoretical and has not been seen in practice.
Fix that by moving the call to net_pkt_ref() just before re-enabling
the interruptions.

The SAM E70 Ethernet driver uses scatter gather DMA to transmit data.
Each fragment of a network packet is mapped from a set of descriptors
that is used by the controller to do the DMA transfer. Each descriptor
contain an address and a length/status. The important status bits are
GMAC_TXW1_LASTBUFFER to indicate the last fragment of a packet and
GMAC_TXW1_USED to indicate that a descriptor has been processed by the
controller.
When starting a transmission, the controller start at the descriptor
after the last one that has been processed. If the descriptor is NOT
flagged by GMAC_TXW1_USED, it sends a first packet by sending all the
fragments up to a descriptor flagged with GMAC_TXW1_LASTBUFFER. The
first descriptor of a packet *and only the first descriptor of a packet*
is then modified to flag it with GMAC_TXW1_USED and to provide a status
(mostly related to errors and checksum offloading). It then continues
with the next packet and so on and only stops if the next descriptor
after GMAC_TXW1_LASTBUFFER is flagged with GMAC_TXW1_USED.
Therefore in order for the controller to stop processing descriptors,
the strategy is to flag the next descriptor after the last fragment to
be sent with GMAC_TXW1_USED. When the next packet has to be queued, the
flag can be removed before starting a transmission.
This is what is currently done in the current driver. However there is a
small race condition in the implementation: if packets are queued fast
enough, the controller is still sending the fragment of the previous
packet when the descriptor are written. When writing the first
descriptor, the GMAC_TXW1_USED flag is removed. This is done after
writing the address (with a memory barrier) so that looks safe. However
given that the GMAC_TXW1_USED flag is only added by the controller to
the first descriptor of a packet it means the next descriptor might
have it cleared. In that case the descriptor is processed, and a junk
packet is sent. That also desynchronize eth_tx and tx_complete as one
or more packets than expected are transmitted.
In order to fix that the strategy is slightly changed to initially write
the first descriptor with the GMAC_TXW1_USED flag set. Once all the
descriptors from the packet are written the bit is cleared (after a
memory barrier). Then the transmission can be started safely.
The patch also does a small optimization writing the next descriptor
with only the GMAC_TXW1_USED bit set instead of setting this bit. As
this will be a non-cached area, it's better avoiding a read followed
by a write if not necessary.

If a pkt has more frags than the number of TX descriptors, we end up in
a deadlock situation, as the whole packet and thus all the frags have to
be mapped in the descriptors at once. That is why the number of
descriptors is defined as CONFIG_NET_BUF_TX_COUNT + 1.
This wrongly assumes that only TX buffers can be used to send data,
however the packets might also come from the RX buffers, like for
example with ICMPv4.
Therefore define the number of descriptors as the maximum of
CONFIG_NET_BUF_RX_COUNT + 1 and CONFIG_NET_BUF_TX_COUNT + 1. This fixes
a deadlock when CONFIG_NET_BUF_TX_COUNT is much smaller than
CONFIG_NET_BUF_RX_COUNT.

The current SAM E70 Ethernet driver sometimes get stuck if the stack
has to send 2 packets in a row, for example an ack for the just received
data + answer data.
The problem is the following one:
1) The first packet goes through eth_tx, one tx_desc_sem semaphore is
taken, and the tx_timeout_work delayed work is submitted.
2) The second packet also goes through eth_tx, another tx_desc_sem
semaphore is taken, and the tx_timeout_work delayed work is not
started because there is already one already submitted.
3) The first packet has been sent, one tx_desc_sem semaphore is given
and the tx_timeout_work delayed work is cancelled.
4) The second packet has been sent but given the delayed work has
already been cancelled, tx_completed is not called: the tx_desc_sem
semaphore is not given back and the network packet is not
unreferenced.
The whole timeout concept probably has to be reworked. In the meantime
it is probably better to just drop the timeout code instead of keeping
the driver broken. We can only get stuck on the TX path if there is a
bug in the driver or a hardware malfunction. It might happen, but with
the less probability then the current hangs. In addition it just hides
the real issues and prevent them to be fixed.
This commit therefore just remove the timeout code in the TX path.

Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.
There are at least three problems with the patch:
1. It's inconsistent with how Kconfig works in other projects, which
might confuse newcomers.
2. Due to oversights, earlier 'range' properties are still preferred,
as well as earlier 'default' properties on choices.
In addition to being inconsistent, this makes it impossible to
override 'range' properties and choice 'default' properties if the
base definition of the symbol/choice already has 'range'/'default'
properties.
I've seen errors caused by the inconsistency, and I suspect there
are more.
3. A fork of Kconfiglib that adds the patch needs to be maintained.
Get rid of the patch and go back to standard Kconfig behavior, as
follows:
1. Include the Kconfig.defconfig files first instead of last in
Kconfig.zephyr.
2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
last in arch/Kconfig.
3. Include arch/<arch>/soc/*/Kconfig first instead of last in
arch/<arch>/Kconfig.
4. Swap a few other 'source's to preserve behavior for some scattered
symbols with multiple definitions.
Swap 'source's in some no-op cases too, where it might match the
intent.
5. Reverse the defaults on symbol definitions that have more than one
default.
Skip defaults that are mutually exclusive, e.g. where each default
has an 'if <some board>' condition. They are already safe.
6. Remove the prefer-later-defaults patch from Kconfiglib.
Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions
As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).
This commit includes some default-related cleanups as well:
- Simplify some symbol definitions, e.g. where a default has 'if FOO'
when the symbol already has 'depends on FOO'.
- Remove some redundant 'default ""' for string symbols. This is the
implicit default.
Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).
Piggyback some fixes for style nits too, e.g. unindented help texts.

There are too many individual requests for Qav related parameters. There
are more Qav parameters that need to be supported (and will be supported
soon - both on the GET and SET side). Handling it the way it was handled
so far would render the eth mgmt API dominated by Qav parameters. That
would make the file hard to read and understand.
Instead of that - use a single GET and SET requests for all Qav
parameters. This works by adding a separate enum with Qav request type
to the ethernet_qav_param struct.
Additionally this approach makes it much easier to document it all since
we now have just a single request and documentation comments in the
ethernet_qav_param struct.

This commit makes the driver enable HW Qav support for all available
priority queues.
Note that the hardware doesn't support setting the deltaBandwidth
parameter directly, but it is possible to do this by calculating it
from the negotiated link speed.
The default settings are set according to 802.1Qav 34.3.1, that says:
The recommended default value of deltaBandwidth(N) for the highest
numbered traffic class supported is 75%, and for any lower
numbered traffic classes, the recommended default value is 0%.
The default/recommended values can be changed using the ethernet

The previous default, CONFIG_ETH_MCUX_0_RANDOM_MAC, result in a random
MAC address changed each reboot. As reboots happen quite often during
development, while Ethernet peers usually cache existing MAC addresses
in ARP cache, this led to situation when a board after reboot didn't
respond to pings or any other connection attempts for random amount of
time (upo to 10-20s). This was quite confusing and looked like some
problem in driver/hardware/connection/whatever.
Instead, introduce new option, CONFIG_ETH_MCUX_0_UNIQUE_MAC, to make
MAC address from MCU unique identification register. This results in
randomized/unique MAC address which is also stable over reboots and
avoids the situation described above.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
