205983c437 sit: allow to use rtnl ops on fb tunnel
rtnl ops where introduced by ba3e3f50a0 ("sit: advertise tunnel param via
rtnl"), but I forget to assign rtnl ops to fb tunnels.

Now that it is done, we must remove the explicit call to
unregister_netdevice_queue(), because  the fallback tunnel is added to the queue
in sit_destroy_tunnels() when checking rtnl_link_ops of all netdevices (this
is valid since commit 5e6700b3bf ("sit: add support of x-netns")).

Jeff Kirsher says:

====================
This series contains updates to ixgbevf, ixgbe and igb.

Don provides 3 patches for ixgbevf where he cleans up a redundant
read mailbox failure check, adds a new function to wait for receive
queues to be disabled before disabling NAPI, and move the API
negotiation so that it occurs in the reset path.  This will allow
the PF to be informed of the API version earlier.

Jacob provides a ixgbevf and ixgbe patch.  His ixgbevf patch removes
the use of hw_dbg when the ixgbe_get_regs function is called in ethtool.
The ixgbe patch renames the LL_EXTENDED_STATS and some of the functions
required to implement busy polling in order to remove the marketing
"low latency" blurb which hides what the code actually does.

Leonardo provides a ixgbe patch to add support for DCB registers dump
using ethtool for 82599 and x540 ethernet controllers.

I (Jeff) provide a ixgbe patch to cleanup whitespace issues seen in a
code review.

Todd provides for igb to add support for i354 in the ethtool offline
tests.

Laura provides an igb patch to add the ethtool callbacks necessary to
configure the number of RSS queues.

b4640030ec ixgbe: remove marketing names from busy poll code
This patch renames the LL_EXTENDED_STATS and some of the functions required to
implement busy polling in the ixgbe driver, in order to remove the marketing
"low latency" blurb which hides what the code actually does.

This furthers work which was requested by Linus Torvalds when the initial busy
poll code was included in the kernel. The code in the ixgbe driver itself was
never properly renamed to reflect the change to busy polling as the title.

This fails to be effective when there's only TX and no RX.

- Calculating EQ-delay based on both RX and TX pps.
- Modifying EQ-delay of all EQs via one cmd, instead of issuing a separate
  cmd for each EQ.
- A new structure to store interrupt coalescing parameters, in a separate

fallback device twice in ip_tunnel_destroy(). The first
time when we queue all netdevices in the namespace and
then again explicitly. Fix this by removing the explicit

Bug was introduced when network namespace support was added

If a packet is on the buffer when temac_stop is called, the dma
descriptors indexes can be left on a incorrect state where no other

So an interface could be left in an usable state after ifdow/ifup.

131a19bc92 regulatory: enable channels 52-64 and 100-144 for world roaming
If allowed in a country, these channels typically require DFS
so mark them as such. Channel 144 is a bit special, it's coming
into use now to allow more VHT 80 channels, but world roaming
with passive scanning is acceptable anyway. It seems fairly
unlikely that it'll be used as the control channel for a VHT
AP, but it needs to be present to allow a full VHT connection
to an AP that uses it as one of the secondary channels.

Also enable VHT 160 on these channels, and also for channels
36-48 to be able to use VHT 160 there.

180cf72f56 netfilter: nf_ct_sip: consolidate NAT hook functions
There are currently seven different NAT hooks used in both
nf_conntrack_sip and nf_nat_sip, each of the hooks is exported in
nf_conntrack_sip, then set from the nf_nat_sip NAT helper.

And because each of them is exported there is quite some overhead

0cfcefef19 mac80211: support reporting A-MSDU subframes individually
Some devices may not be able to report A-MSDUs in
single buffers. Drivers for such devices were
forced to re-assemble A-MSDUs which would then
be eventually disassembled by mac80211. This could
lead to CPU cache thrashing and poor performance.

Since A-MSDU has a single sequence number all
subframes share it. This was in conflict with
retransmission/duplication recovery
(IEEE802.11-2012: 9.3.2.10).

Patch introduces a new flag that is meant to be
set for all individually reported A-MSDU subframes
except the last one. This ensures the
last_seq_ctrl is updated after the last subframe
is processed. If an A-MSDU is actually a duplicate
transmission all reported subframes will be
properly discarded.

4590672357 skbuff: size of hole is wrong in a comment
Since commit c93bdd0e03 ("netvm: allow skb allocation to use PFMEMALLOC
reserves"), hole size is one bit less than what is written in the comment.

9260d3e101 ipv6 mcast: use in6_dev_put in timer handlers instead of __in6_dev_put
It is possible for the timer handlers to run after the call to
ipv6_mc_down so use in6_dev_put instead of __in6_dev_put in the
handler function in order to do proper cleanup when the refcnt
reaches 0. Otherwise, the refcnt can reach zero without the
inet6_dev being destroyed and we end up leaking a reference to
the net_device and see messages like the following,

unregister_netdevice: waiting for eth0 to become free. Usage count = 1

Tested on linux-3.4.43.

b324187051 bonding: RCUify bond_set_rx_mode()
Currently we rely on rtnl locking in bond_set_rx_mode(), however it's not

Fix this by using RCU primitives.

437a3ae1d0 ethernet: moxa: fix incorrect placement of __initdata tag
__initdata tag should be placed between the variable name and equal
sign for the variable to be placed in the intended .init.data section.

In this particular case __initdata is incorrect as moxart_mac_driver
can be used after the driver gets initialized.

Also while at it static-ize moxart_mac_driver.
