These pernet_operations unregister ipvlan net hooks.
nf_unregister_net_hooks() removes hooks one-by-one,
and then frees the memory via rcu. This looks similar
to that happens, when a new hooks is added: allocation
of bigger memory region, copy of old content, and rcu
freeing the old memory. So, all of net code should be
well with this behavior. Also at the time of hook
unregistering, there are no packets, and foreign net
pernet_operations are not interested in others hooks.
So, we mark them as async.

10GbE Intel Wired LAN Driver Updates 2018-02-26
This series contains updates to ixgbe and ixgbevf only.
Colin Ian King cleans up redundant variable assignments.
Tonghao Zhang updates ixgbe to avoid writing to the hardware when the
redirection table has not changed.
Jake fixes the driver logic for checking and clearing receive timestamp
hangs so that when the PTP_RX_TIMESTAMP_IN_REGISTER flag is set, we no
longer need to check for receive timestamp hangs, which in turn will
stop the spurious log messages.
Emil updates ixgbevf with several features and improvements done in
other drivers, starting with the handling of page addresses so that we
always refer to them using a void pointer. Added a 'legacy-rx' flag to
allow switching between the old and new receive code paths. Added
support for using 3K buggers in order 1 page. Updated the driver to
ensure that calls to ixgbevf_open() are rtnl lock protected and improved
the error handling when setting up multiple queues. Added support for
providing a buffer with head room and tail room to allow for shared
info, NET_SKB_PAD, and NET_IP_ALIGN, so that we can start using
build_skb to build frames instead of using memcpy() the headers.
Updated the logic of handling rings closer to ixgbe. Consolidated the
receive paths to reduce duplication when we expand them in the future.
Added build_skb() support to ixgbevf.

It appears that the single port Ether controllers having TSU (like SH7734/
R8A7740) need the same kind of treating in sh_eth_tsu_init() as R7S72100

passing the frames between ports. Add the 'sh_eth_cpu_data::dual_port'
flag and use it as a new criterion for taking a "short path" in the TSU
init sequence in order to avoid writing to the non-existent registers...

have the same long name as the TSU_QTAGM0/1 registers in the early Ether
controllers: Qtag Addition/Deletion Set Register (Port 0/1 to 1/0); thus
there's no need to make a difference in sh_eth_tsu_init() between those

On hardware which supports timestamping all packets, the timestamps are
recorded in the packet buffer, and the driver no longer uses or reads
the registers. This makes the logic for checking and clearing Rx
timestamp hangs meaningless.
If we run the ixgbe_ptp_rx_hang() function in this case, then the driver
will continuously spam the log output with "Clearing Rx timestamp hang".
These messages are spurious, and confusing to end users.
The original code in commit a9763f3cb5 ("ixgbe: Update PTP to support
X550EM_x devices", 2015-12-03) did have a flag PTP_RX_TIMESTAMP_IN_REGISTER
which was intended to be used to avoid the Rx timestamp hang check,
however it did not actually check the flag before calling the function.
Do so now in order to stop the checks and prevent the spurious log
messages.

Not all boards have the interrupt output from the switch connected to
a GPIO line. In such cases, phylib has to poll the internal PHYs,
rather than receive an interrupt when there is a change in the link
state. phylib polls once per second, and per PHY reads around 4
words. With a switch typically having 4 internal PHYs, this means 16
MDIO transactions per second.
Rather than performing this phylib level polling, have the driver poll
the interrupt status register. If the status register indicates an
interrupt condition processing of interrupts in the same way as if a
GPIO was used.
Polling 10 times a second places less load on the MDIO bus. But rather
than taking on average 0.5s to detect a link change, it takes less
than 0.05s. Additionally, other interrupts, such as the watchdog, ATU
and VTU violations will be reported.

Up until now we only allowed VLAN devices to be put in a VLAN-unaware
bridge, but some users need the ability to enslave physical ports as
well.
This is achieved by mapping the port and VID 1 to the bridge's vFID,
instead of the port and the VID used by the VLAN device.
The above is valid because as long as the port is not enslaved to a
bridge, VID 1 is guaranteed to be configured as PVID and egress
untagged.

Currently, if BIOS enables WOL in the chip, settings are inconsistent
because the device isn't marked as wakeup-enabled (if not done
explicitly via userspace tools). This causes issues with suspend/
resume because mdio_bus_phy_may_suspend() checks whether device is
wakeup-enabled. In detail MDIO bus access in phy_suspend() can fail
because the MDIO bus is disabled.
In the history of the driver we find two competing approaches:
8f9d513803 "r8169: remember WOL preferences on driver load" prefers
to preserve what the BIOS may have set, whilst bde135a672
"r8169: only enable PCI wakeups when WOL is active" disabled PCI
wakeup per default to work around a bug on one platform.
Seems like nobody complained after the latter patch about non-working
WOL, what makes me think that nobody uses WOL w/o configuring it
explicitly.
My opinion:
Vast majority of users doesn't use WOL even if the BIOS enables it in
the chip. And having WOL being active keeps the PHY(s) from powering
down if being idle.
If somebody needs WOL, he can enable it during boot, e.g. by
configuring systemd.link/WakeOnLan.
Therefore, to make WOL consistent again, disable it per default.

Fixing this inside gfar_add_rx_frag() is difficult due to reserved

gfar_process_frame() and trim off the FCS before passing the skb up the

The approach of one counter to rule them all when tracking the number
of active sub-crqs, pools, and napi has problems handling some failover
scenarios. This is due to the split in initializing the sub crqs,
pools and napi in different places and the placement of updating
the active counts.
This patch simplifies this by having a counter for tx and rx
sub-crqs, pools, and napi.

MV88E6352 and later switches support GPIO control through the "Scratch
& Misc" global2 register. Two of the pins controlled this way on the
mv88e6390 family are the external MDIO pins. They can either by used
as part of the MII interface for port 0, GPIOs, or MDIO. Add a
function to configure them for MDIO, if possible, and call it when
registering the external MDIO bus.
