NEXTHDR_MAX is 255. What happens here is that we take a u8 value
"hdr->nexthdr" from the network and then look it up in
lowpan_nexthdr_nhcs[]. The problem is that if hdr->nexthdr is 0xff then
we read one element beyond the end of the array so the array needs to
be one element larger.

The BCM43341B has the default MAC address 43:34:1B:00:1F:AC if none
is given. This address was found when enabling Bluetooth on multiple
Intel Edison modules. It also contains the sequence 43341B, the name
the chip identifies itself as. Using the same BD_ADDR is problematic
when having multiple Intel Edison modules in each others range.
The default address also has the LAA (locally administered address)
bit set which prevents a BNEP device from being created, needed for
BT tethering.
Add this to the list of black listed default MAC addresses and let
the user configure a valid one using f.i.

Currently, there are many independent programming sequences from the

mlxsw: Shared buffer improvements
This patchset includes two improvements with regards to shared buffer
configuration in mlxsw.
The first part of this patchset forbids the user from performing illegal
shared buffer configuration that can result in unnecessary packet loss.
In order to better communicate these configuration failures to the user,
extack is propagated from devlink towards drivers. This is done in
patches #1-#8.
The second part of the patchset deals with the shared buffer
configuration of the CPU port. When a packet is trapped by the device,
it is sent across the PCI bus to the attached host CPU. From the
device's perspective, it is as if the packet is transmitted through the
CPU port.
While testing traffic directed at the CPU it became apparent that for
certain packet sizes and certain burst sizes, the current shared buffer
configuration of the CPU port is inadequate and results in packet drops.
The configuration is adjusted by patches #9-#14 that create two new pools
- ingress & egress - which are dedicated for CPU traffic.

Use the new ingress pool that was added in the previous patch for
control packets (e.g., STP, LACP) that are trapped to the CPU.
The previous management pool is no longer necessary and therefore its
size is set to 0.
The maximum quota for traffic towards the CPU is increased to 50% of the
free space in the new ingress pool and therefore the reserved space is
reduced by half, to 10KB - in both the shared and headroom buffer. This
allows for more efficient utilization of the shared buffer as reserved
space cannot be used for other purposes.

Paul Gortmaker says:
====================
clean up needless use of module infrastructure
People can embed modular includes and modular exit functions into code
that never use any of it, and they won't get any errors or warnings.
Using modular infrastructure in non-modules might seem harmless, but some
of the downfalls this leads to are:
(1) it is easy to accidentally write unused module_exit removal code
(2) it can be misleading when reading the source, thinking a driver can
be modular when the Makefile and/or Kconfig prohibit it
(3) an unused include of the module.h header file will in turn
include nearly everything else; adding a lot to CPP overhead.
(4) it gets copied/replicated into other drivers and spreads quickly.
As a data point for #3 above, an empty C file that just includes the
module.h header generates over 750kB of CPP output. Repeating the same
experiment with init.h and the result is less than 12kB; with export.h
it is only about 1/2kB; with both it still is less than 12kB. One driver
in this series gets the module.h ---> init.h+export.h conversion.
Worse, are headers in include/linux that in turn include <linux/module.h>
as they can impact a whole fleet of drivers, or a whole subsystem, so
special care should be used in order to avoid that. Such headers should
only include what they need to be stand-alone; they should not be trying
to anticipate the various header needs of their possible end users.
In this series, four include/linux headers have module.h removed from
them because they don't strictly need it. Then three chunks of net
related code have modular infrastructure that isn't used, removed.
There are no runtime changes, so the biggest risk is a genuine consumer
of module.h content relying on implicitly getting it from one of the
include/linux instances removed here - thus resulting in a build fail.
With that in mind, allmodconfig build testing was done on x86-64, arm64,
x86-32, arm. powerpc, and mips on linux-next (and hence net-next).

The Kconfig currently controlling compilation of this code is:

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit. For
clarity, we change the fcn name mod_init to dev_init at the same time.
We replace module.h with init.h and export.h ; the latter since this

module support.
There doesn't appear to be anything in psample.h that is module
related, and build coverage doesn't appear to show any other
files/drivers relying implicitly on getting it from here.
So it appears we are simply free to just remove it in this case.

The header contains rtnh_ macros so rename the file accordingly.
Allows a later patch to use the nexthop.h name for the new
nexthop code.

This patch makes trivial whitespace fix to the function
tcp_v4_check at include/net/tcp.h file.
It has stylistic issue, which is "space required after that ','"
and it can be confirmed with ./scripts/checkpatch.pl tool.
ERROR: space required after that ',' (ctx:VxV)
