The socket option will be enabled by default to ensure current behaviour
is not changed. This is the same for the IPv4 version.
A socket bound to in6addr_any and a specific port will receive all traffic
on that port. Analogue to IP_MULTICAST_ALL, disable this behaviour, if
one or more multicast groups were joined (using said socket) and only
pass on multicast traffic from groups, which were explicitly joined via
this socket.
Without this option disabled a socket (system even) joined to multiple
multicast groups is very hard to get right. Filtering by destination
address has to take place in user space to avoid receiving multicast
traffic from other multicast groups, which might have traffic on the same
port.
The extension of the IP_MULTICAST_ALL socketoption to just apply to ipv6,
too, is not done to avoid changing the behaviour of current applications.

Similar with commit 72f6d71e49 ("vxlan: add ttl inherit support"),
currently ttl == 0 means "use whatever default value" on geneve instead
of inherit inner ttl. To respect compatibility with old behavior, let's
add a new IFLA_GENEVE_TTL_INHERIT for geneve ttl inherit support.

This adds a new IFA_TARGET_NETNSID property to be used by address
families such as PF_INET and PF_INET6.
The IFA_TARGET_NETNSID property can be used to send a network namespace
identifier as part of a request. If a IFA_TARGET_NETNSID property is
identified it will be used to retrieve the target network namespace in
which the request is to be made.

Currently, the only way to ignore outgoing packets on a packet socket is
via the BPF filter. With MSG_ZEROCOPY, packets that are looped into
AF_PACKET are copied in dev_queue_xmit_nit(), and this copy happens even
if the filter run from packet_rcv() would reject them. So the presence
of a packet socket on the interface takes away the benefits of
MSG_ZEROCOPY, even if the packet socket is not interested in outgoing
packets. (Even when MSG_ZEROCOPY is not used, the skb is unnecessarily
cloned, but the cost for that is much lower.)
Add a socket option to allow AF_PACKET sockets to ignore outgoing
packets to solve this. Note that the *BSDs already have something
similar: BIOCSSEESENT/BIOCSDIRECTION and BIOCSDIRFILT.
The first intended user is lldpd.

Drivers able to correctly replace a in-use key should set
@NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to allow the user space (e.g.
hostapd or wpa_supplicant) to rekey PTK keys.
The user space must detect a PTK rekey attempt and only go ahead with it
when the driver has set this flag. If the driver is not supporting the
feature the user space either must not replace the PTK key or perform a
full re-association instead.
Ignoring this flag and continuing to rekey the connection can still work
but has to be considered insecure and broken. Depending on the driver it
can leak clear text packets or freeze the connection and is only
supported to allow the user space to be updated.

tokens and ctokens are defined as s64 in htb_class structure,
and clamped to 32bits value during netlink dumps:
cl->xstats.tokens = clamp_t(s64, PSCHED_NS2TICKS(cl->tokens),
INT_MIN, INT_MAX);
Defining it as u32 is working since userspace (tc) is printing it as
signed int, but a correct definition from the beginning is probably
better.
In the same time, 'giants' structure member is unused since years, so
update the comment to mark it unused.
