bonding: remove the return value for bond_3ad_bind_slave()

I'm sure the operand slave and bond for the function will not
be NULL, so the check for the bond will not make any sense, so
remove the judgement, and the return value was useless here,
remove the unwanted return value.

Merge branch 'addr_compare'

Ding Tianhong says:

====================
slight optimization of addr compare for net modules

This is the second patchset for slight optimization of address compare,
mainly for net tree, just following the Joe's opinion, it will help review
the code for maintainers and supports.

v2: Change some style for patch 2.
    According Eric's suggestion, use the ether_addr_equal_64bits to instead
    of ether_addr_equal for patch 19.
    In fact, there are a lot of places which could use ether_addr_equal_64bits
    to instead of ether_addr_equal, but not this time, thanks for Joe's
    opinion.

v3: Change some style for patch 11/19:
    (net: packetengines: slight optimization of addr compare).
    Joe pointed out that is_broadcast_ether_addr(addr) would be appropriate here,
    but this should be left alone and not in this patch, so fix it later.

    In the patch (net: caif: slight optimization of addr compare), the operand for
    memcmp is not mac address, so it is unsuitable to use the ether_addr_equal
    to compare a non mac address, so remove the patch from the series.

netlink: specify netlink packet direction for nlmon

In order to facilitate development for netlink protocol dissector,
fill the unused field skb->pkt_type of the cloned skb with a hint
of the address space of the new owner (receiver) socket in the
notion of "to kernel" resp. "to user".

At the time we invoke __netlink_deliver_tap_skb(), we already have
set the new skb owner via netlink_skb_set_owner_r(), so we can use
that for netlink_is_kernel() probing.

In normal PF_PACKET network traffic, this field denotes if the
packet is destined for us (PACKET_HOST), if it's broadcast
(PACKET_BROADCAST), etc.

As we only have 3 bit reserved, we can use the value (= 6) of
PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel
and not supported anywhere, and packets of such type were never
exposed to user space, so there are no overlapping users of such
kind. Thus, as wished, that seems the only way to make both
PACKET_* values non-overlapping and therefore device agnostic.

By using those two flags for netlink skbs on nlmon devices, they
can be made available and picked up via sll_pkttype (previously
unused in netlink context) in struct sockaddr_ll. We now have
these two directions:

 - PACKET_USER (= 6)    ->  to user space
 - PACKET_KERNEL (= 7)  ->  to kernel space

Partial `ip a` example strace for sa_family=AF_NETLINK with
detected nl msg direction:

syscall:                     direction:
sendto(3,  ...) = 40         /* to kernel */
recvmsg(3, ...) = 3404       /* to user */
recvmsg(3, ...) = 1120       /* to user */
recvmsg(3, ...) = 20         /* to user */
sendto(3,  ...) = 40         /* to kernel */

We should also deliver packets to nlmon devices when we are in
netlink_unicast_kernel(), and only one of the {src,dst} sockets
is user sk and the other one kernel sk. That's e.g. the case in
netlink diag, netlink route, etc. Still, forbid to deliver messages

Merge branch 'sctp_logspam'

Neil Horman says:

====================
sctp: Consolidate and ratelimit deprecation warnings

The SCTP protocol has several deprecation warnings in its setsockopt path that
can be triggered by unprivlidged users.  Since these are not ratelimited, we can
spam the logs quite easily here.  Since these are all deprecation warnings, and
that type of warning isn't uncommon in the rest of the kernel, lets make a
common pr_warn_deprecated macro to produce somewhat generalized ratelimited
deprecation warnings easily

SCTP: Reduce log spamming for sctp setsockopt

During a recent discussion regarding some sctp socket options, it was noted that
we have several points at which we issue log warnings that can be flooded at an
unbounded rate by any user.  Fix this by converting all the pr_warns in the
sctp_setsockopt path to be pr_warn_ratelimited.

Note there are several debug level messages as well.  I'm leaving those alone,
as, if you turn on pr_debug, you likely want lots of verbosity.

tun: Add support for RFS on tun flows

This patch adds support so that the rps_flow_tables (RFS) can be
programmed using the tun flows which are already set up to track flows
for the purposes of queue selection.

On the receive path (corresponding to select_queue and tun_net_xmit) the
rxhash is saved in the flow_entry.  The original code only does flow
lookup in select_queue, so this patch adds a flow lookup in tun_net_xmit
if num_queues == 1 (select_queue is not called from
dev_queue_xmit->netdev_pick_tx in that case).

The flow is recorded (processing CPU) in tun_flow_update (TX path), and
reset when flow is deleted.
