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,
based on the context.

Move from a Kconfig to select/initialize the MAC address to using the
"local-mac-address" property in devicetree. If the property is set the
drivers will initialize the mac-address from the devicetree (unless the
mac address is all 0's). The MAC address might get overwritten by
either a driver specific means or by the setting of
"zephyr,random-mac-address" in the devicetree.

This option is meant to be used only for debugging. Use it to force all
traffic to be routed through a specific hardware queue. With this option
enabled it is easier to verify whether the chosen hardware queue
actually works.
This works only if there are four or fewer RX traffic classes enabled as

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.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some

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.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.

This patch is the first of a serie that will separate completely net_pkt
from net_buf.
