Add a generic netlink family for NCSI. This supports three commands;
NCSI_CMD_PKG_INFO which returns information on packages and their
associated channels, NCSI_CMD_SET_INTERFACE which allows a specific
package or package/channel combination to be set as the preferred
choice, and NCSI_CMD_CLEAR_INTERFACE which clears any preferred setting.

Since commit 02d742f4b2 ("media: lirc: lirc daemon fails to detect raw
IR device"), the feature LIRC_CAN_SEND_SCANCODE is no longer used as it
tripped up lircd. The ability to send scancodes for IR Tx is implied by
LIRC_CAN_SEND_PULSE (i.e. any device that can send can use IR Tx encoders).
So, remove LIRC_CAN_SEND_SCANCODE since it never used. This fixes:
Documentation/output/lirc.h.rst:6: WARNING: undefined label:
lirc-can-send-scancode (if the link has no caption the label must precede

As this flag was added for kernel 4.16, let's remove it, while not too

Currently GRE sequence number can only be used in native
tunnel mode. This patch adds sequence number support for
gre collect metadata mode. RFC2890 defines GRE sequence
number to be specific to the traffic flow identified by the
key. However, this patch does not implement per-key seqno.
The sequence number is shared in the same tunnel device.
That is, different tunnel keys using the same collect_md
tunnel share single sequence number.

The documentation for the ctm matrix suggests a two's complement
format, but at least the i915 implementation is using sign-magnitude
instead. And looks like malidp is doing the same. Change the docs
to match the current implementation, and change the type from __s64

This commit is an optimization over commit 01883eda72
("rds: support for zcopy completion notification") for PF_RDS sockets.
RDS applications are predominantly request-response transactions, so
it is more efficient to reduce the number of system calls and have
zerocopy completion notification delivered as ancillary data on the
POLLIN channel.
Cookies are passed up as ancillary data (at level SOL_RDS) in a
struct rds_zcopy_cookies when the returned value of recvmsg() is
greater than, or equal to, 0. A max of RDS_MAX_ZCOOKIES may be passed
with each message.
This commit removes support for zerocopy completion notification on
MSG_ERRQUEUE for PF_RDS sockets.

NIC drivers generally try to ensure that the "network header" is aligned
to a 4-byte boundary. This is not always possible: When Ethernet frames are
encapsulated in other packets with 4-byte aligned headers, the inner
Ethernet header will have 4-byte alignment, and in consequence, the inner
network header is aligned to 2, but not to 4 bytes.
Most parts of batman-adv only care about 2-byte alignment; in particular,
no unaligned accesses occur in performance-critical paths that handle
actual payload data. This is not true for OGM handling: the seqno and crc
fields are accessed as 32-bit values. To avoid these unaligned accesses,
this patch reduces the expected packet alignment to 2 bytes for all of
batadv's packet types.
As no unaligned accesses existed on the performance-critical paths anyways,
this chance does have any (positive or negative) effect on performance, but
it still makes sense to avoid these accesses to prevent log noise when
examining other unaligned accesses in the kernel while batman-adv is
active.

The media.h public header is very messy. It mixes legacy and 'new' defines
and it is not easy to figure out what should and what shouldn't be used. It
also contains confusing comment that are either out of date or completely
uninteresting for anyone that needs to use this header.
The patch groups all entity functions together, including the 'old' defines
based on the old range base. The reader just wants to know about the available
functions and doesn't care about what range is used.
All legacy defines are moved to the end of the header, so it is easier to
locate them and just ignore them.
The legacy structs in the struct media_entity_desc are put under
also a much more effective signal to the reader that they shouldn't be used
compared to the old method of relying on '#if 1' followed by a comment.
The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header
in the legacy area. They are also dropped from intf_type() in media-entity.c.
All defines are also aligned at the same tab making the header easier to read.

The v4l2_mbus_fmt width and height corresponds directly with the
v4l2_pix_format definitions, yet the differences in documentation make
it ambiguous what to do in the event of field heights.
Clarify this using the same text as is provided for the v4l2_pix_format
which is explicit on the matter, and by matching the terminology of
'image height' rather than the misleading 'frame height'.

For ages iproute2 has used `struct rtmsg` as the ancillary header for
FIB rules and in the process set the protocol value to RTPROT_BOOT.
Until ca56209a66 ("net: Allow a rule to track originating protocol")
the kernel rules code ignored the protocol value sent from userspace
and always returned 0 in notifications. To avoid incompatibility with
existing iproute2, send the protocol as a new attribute.

Commit 26500475ac ("ptrace, seccomp: add support for retrieving seccomp
metadata") introduced `struct seccomp_metadata`, which contained unsigned
longs that should be arch independent. The type of the flags member was
chosen to match the corresponding argument to seccomp(), and so we need
something at least as big as unsigned long. My understanding is that __u64
should fit the bill, so let's switch both types to that.
While this is userspace facing, it was only introduced in 4.16-rc2, and so
should be safe assuming it goes in before then.

The protocol is handled just like a routes originating

The commit a new tc ematch for using netfilter xtable matches.
This allows early classification as well as mirroning/redirecting traffic
based on logic implemented in netfilter extensions.
Current supported use case is classification based on the incoming IPSec
state used during decpsulation using the 'policy' iptables extension
(xt_policy).
The module dynamically fetches the netfilter match module and calls
it using a fake xt_action_param structure based on validated userspace
provided parameters.
As the xt_policy match does not access skb->data, no skb modifications
are needed on match.
