The header file is used by different userspace programs to inject packets
or to decode sniffed packets. It should therefore be available to them as
userspace header.
Also other components in the kernel (like the flow dissector) require
access to the packet definitions to be able to decode ETH_P_BATMAN ethernet
packets.

Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new
count in a field of MC_CMD_GET_CAPABILITIES_V4. This also means that the
end generation count moves (it is, as before, the last 64 bits of the DMA
buffer, but that is no longer MC_CMD_MAC_GENERATION_END).
So read num_mac_stats from the GET_CAPABILITIES response, if present;
otherwise assume MC_CMD_MAC_NSTATS; and always use num_mac_stats - 1 rather
than MC_CMD_MAC_GENERATION_END.

net: sched: sch: introduce extack support
this patch series basically add support for extack in common qdisc handling.
Additional it adds extack pointer to common qdisc callback handling this
offers per qdisc implementation to setting the extack message for each
failure over netlink.
The extack message will be set deeper in qdisc functions but going not
deeper as net core api. For qdisc module callback handling, the extack
will not be set. This will be part of per qdisc extack handling.
I also want to prepare patches to handle extack per qdisc module...
so there will come a lot of more patches, just cut them down to make
it reviewable.
There are some above 80-chars width warnings, which I ignore because
it looks more ugly otherwise.
This patch-series based on patches by David Ahern which gave me some
hints how to deal with extack support.

changes since v4:
- rebase on current net-next/master
- fix several typos (also David Ahren to Ahern, I am sorry)
- Add acked by Jamal
changes since v3:
- remove patch 2/2 lib: nlattr: set extack msg if validate_nla fails since
David Ahern has a better solution
- Remove check on net admin permission since -EPERM indicates it already
- Change rtab to "rate table" - this is what it's stands for
- Fix cbs *not* support messages
- Fix tcf block error message for allocation, allocation will be still there
because there are multiple places which returns -ENOMEM
- Finnally also took care about sch_atm, sorry somehow I forgot this one and
I hope I didn't forgot any sch implementation to add new callback parameters
changes since v2:
- add fix coding style patch to catch all checkpatch warnings
- add patch for setting netlink extack msg if validate_nla fails
- changes in handle generic qdisc errors
- remove NL_SET_ERR_MSG from memory allocation errors
- remove NL_SET_ERR_MSG from device not found
- change STAB to table size
- add various new patches to add extack support for common
TC functions like qdisc_get_rtab, tcf_block_get, qdisc_alloc
and qdisc_create_dflt - users which are interessted in the
detailed error messages can assign extack, otherwise NULL.
- Add sch_cbq as example for qdisc_ops callback: init,
qdisc_class_ops callbacks: change and graft
- Add sch_cbs as example for qdisc_ops callback: change
- Add sch_drr as example for qdisc_class ops callbacks: tcf_block

- counter is initialized to 1 using atomic_set()
- a resource is freed upon counter reaching zero
- once counter reaches zero, its further
increments aren't allowed
- counter schema uses basic atomic operations
(set, inc, inc_not_zero, dec_and_test, etc.)
Such atomic variables should be converted to a newly provided
refcount_t type and API that prevents accidental counter overflows
and underflows. This is important since overflows and underflows
can lead to use-after-free situation and be exploitable.

replace tcp_set_state tracepoint with inet_sock_set_state
According to the discussion in the mail thread
https://patchwork.kernel.org/patch/10099243/,
tcp_set_state tracepoint is renamed to inet_sock_set_state tracepoint and is
moved to include/trace/events/sock.h.
With this new tracepoint, we can trace AF_INET/AF_INET6 sock state transitions.
As there's only one single tracepoint for inet, so I didn't create a new trace
file named trace/events/inet_sock.h, and just place it in
include/trace/events/sock.h
Currently TCP/DCCP/SCTP state transitions are traced with this tracepoint.
- Why not more protocol ?
If we really think that anonter protocol should be traced, I will modify the
code to trace it.
I just want to make the code easy and not output useless information.

With changes in inet_ files, SCTP state transitions are traced with
inet_sock_set_state tracepoint.
As SCTP state names, i.e. SCTP_SS_CLOSED, SCTP_SS_ESTABLISHED,
have the same value with TCP state names. So the output info still print
the TCP state names, that makes the code easy.
