local->radar_detect_enabled should tell whether
radar_detect is enabled on any interface belonging
to local.
However, it's not getting updated correctly
in many cases (actually, when testing with hwsim
it's never been set, even when the dfs master
is beaconing).
Instead of handling all the corner cases
(e.g. channel switch), simply check whether
radar detection is enabled only when needed,
instead of caching the result.

The function adding the supported channels IE during a TDLS connection had
several issues:
1. If the entire subband is usable, the function exitted the loop without
adding it
2. The function only checked chandef_usable, ignoring flags like RADAR
which would prevent TDLS off-channel communcation.
3. HT20 was explicitly required in the chandef, while not a requirement
for TDLS off-channel.

When roaming / suspending, it makes no sense to wait until
the transmit queues of the device are empty. In extreme
condition they can be starved (VO saturating the air), but
even in regular cases, it is pointless to delay the roaming
because the low level driver is trying to send packets to
an AP which is far away. We'd rather drop these packets and
let TCP retransmit if needed. This will allow to speed up
the roaming.
For suspend, the explanation is even more trivial.

====================
add hisilicon hip04 ethernet driver
v13:
- Fix the problem of alignment parameters for function and checkpatch warming.
v12:
- According Alex's suggestion, modify the changelog and add MODULE_DEVICE_TABLE
for hip04 ethernet.
v11:
- Add ethtool support for tx coalecse getting and setting, the xmit_more
is not supported for this patch, but I think it could work for hip04,
will support it later after some tests for performance better.
Here are some performance test results by ping and iperf(add tx_coalesce_frames/users),
it looks that the performance and latency is more better by tx_coalesce_frames/usecs.

v10:
- According Arnd's suggestion, remove the skb_orphan and use the hrtimer
for the cleanup of the TX queue and add some modification for the hip04
drivers.
1) drop the broken skb_orphan call
2) drop the workqueue
3) batch cleanup based on tx_coalesce_frames/usecs for better throughput
4) use a reasonable default tx timeout (200us, could be shorted
based on measurements) with a range timer
5) fix napi poll function return value
6) use a lockless queue for cleanup
v9:
- There is no tx completion interrupts to free DMAd Tx packets, it means taht
we rely on new tx packets arriving to run the destructors of completed packets,
which open up space in their sockets's send queues. Sometimes we don't get such
new packets causing Tx to stall, a single UDP transmitter is a good example of
this situation, so we need a clean up workqueue to reclaims completed packets,
the workqueue will only free the last packets which is already stay for several jiffies.
Also fix some format cleanups.
v8:
- Use poll to reclaim xmitted buffer as workaround since no tx done interrupt
v7:
- Remove select NET_CORE in 0002
v6:
- Suggest by Russell: Use netdev_sent_queue & netdev_completed_queue to solve latency issue
Also shorten the period of timer, which is used to wakeup the queue since no
tx completed interrupt.
v5:
- no big change, fix typo
v4:
- Modify accoringly to the suggetion from Arnd, Florian, Eric, David
Use of_parse_phandle_with_fixed_args & syscon_node_to_regmap get ppe info
Add skb_orphan() and tx_timer for reclaim since no tx_finished interrupt
Update timeout, and move of_phy_connect to probe to reuse open/stop
v3:
- Suggest from Arnd, use syscon & regmap_write/read to replace static void __iomem *ppebase.
Modify hisilicon-hip04-net.txt accrordingly to suggestion from Florian and Sergei.
v2:
- Got many suggestions from Russell, Arnd, Florian, Mark and Sergei
Remove memcpy, use dma_map/unmap_single, use dma_alloc_coherent rather than dma_pool, etc.
Refer property in ethernet.txt, change ppe description, etc.

When setting base_reachable_time or base_reachable_time_ms on a
specific interface through sysctl or netlink, the reachable_time
value is not updated.
This means that neighbour entries will continue to be updated using the
old value until it is recomputed in neigh_period_work (which
recomputes the value every 300*HZ).
On systems with HZ equal to 1000 for instance, it means 5mins before
the change is effective.
This patch changes this behavior by recomputing reachable_time after
each set on base_reachable_time or base_reachable_time_ms.
The new value will become effective the next time the neighbour's timer
is triggered.
Changes are made in two places: the netlink code for set and the sysctl
handling code. For sysctl, I use a proc_handler. The ipv6 network
code does provide its own handler but it already refreshes
reachable_time correctly so it's not an issue.
Any other user of neighbour which provide its own handlers must
refresh reachable_time.

On i.MX28, the MDIO bus is shared between the two FEC instances.
The driver makes sure that the second FEC uses the MDIO bus of the
first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set.
However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC
has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC
is not an option since other logic, triggered by this quirk, is
still needed.
Furthermore, there are board designs which use the same MDIO bus
for both PHY's even though the second bus would be available on the
SoC side. Such layout are popular since it saves pins on SoC side.
Due to the above quirk, those boards currently do work fine. The
boards in the mainline tree with such a layout are:
- Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts)
- Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts)
This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which
makes sure that the MDIO bus of the first FEC is used in any case.
However, the boards above do have a SoC with a MDIO bus for each FEC
instance. But the PHY's are not connected in a 1:1 configuration. A
proper device tree description is needed to allow the driver to
figure out where to find its PHY. This patch fixes that shortcoming
by adding a MDIO bus child node to the first FEC instance, along
with the two PHY's on that bus, and making use of the phy-handle
property to add a reference to the PHY's.

Currently `ethtool -S` simply returns "no stats available". It

registers' values are. This change implements get_ethtool_stats,
get_strings, and get_sset_count functions to accomplish this.
Read all GEM statistics registers and sum them into
macb.ethtool_stats. Add the necessary infrastructure to make this
accessible via `ethtool -S`.

tc code implicitly considers skb->protocol even in case of accelerated
vlan paths and expects vlan protocol type here. However, on rx path,
if the vlan header was already stripped, skb->protocol contains value

So for skbs that use skb->vlan_tci for tagging, use skb->vlan_proto instead.

In netfront the Rx and Tx path are independent and use different

held with only BH disabled. Since both sides use the same stats lock,
a deadlock may occur.

Not all architectures are able to call __builtin_return_address().
On ARM, the mISDN code produces this warning:

hardware/mISDN/w6692.c:1181:75: warning: unsupported argument to '__builtin_return_address'

pr_debug("%s: %s dev(%d) open from %p\n", isac->name, __func__,
^
In a lot of cases, this is relatively easy to work around by
passing the value of __builtin_return_address(0) from the
callers into the functions that want it. One exception is
the indirect 'open' function call in struct isac_hw. While it
would be possible to fix this as well, this patch only addresses
the other callers properly and lets this one return the direct
parent function, which should be good enough.

which '&' is missed in 'mdio_stat &= ~MDIO_STAT_ENC'.

Patch 3b50d9029809 ("ipv6: fix redefinition of in6_pktinfo ...")
fixed a libc compatibility issue in ipv6 structure definitions
as described in include/uapi/linux/libc-compat.h.
It relies on including linux/in6.h to include libc-compat.h itself.
Include that file directly to clearly communicate the dependency
(libc-compat.h: "This include must be as early as possible").

====================
Intel Wired LAN Driver Updates 2015-01-13
This series contains updates to i40e and i40evf.
Mitch provides a fix for i40e to move the call to pci_disable_sriov() so
that it is called earlier to ensure that the PF driver won't free VF
resources before the VF remove routine can complete. Also cleans up
redundant and duplicate code in the i40evf. Refactors the i40evf
shutdown code and let the watchdog take care of shutting things down.
Fix a possible memory leak, if we are using VLANs and the communication
with the PF fail during shutdown. On some versions of the firmware, the
VF admin send queue may become stalled. In this case, the easiest
solution is to place another descriptor on the queue and the firmware
will then process both requests.
Greg adds a warning when the NPAR enabled partitions detected a link speed
less than 10 Gpbs.
Vasu removes redundant VN2VN MAC address which were already added by
the FCoE stack.
Shannon adds code to find how many partitions there are per port and
what is the current partition_id when in NPAR mode. In multifunction
mode, make sure we only allow SR/IOV on the master PF of a port and
only allow partition 1 to set WoL, speed and flow control.
Kamil adds code to read the PBA block from shadow RAM and returns
the part number in a string format.
Catherine provides a fix to check if link state and link speed has
changed before exiting link event
v2: remove un-needed {} in patch #3 of the series based on feedback from
Sergei Shtylyov

Make sure we only allow SR/IOV on the master PF of a port in multifunction
mode. This should be the case anyway based on the num_vfs configured in
the NVM, but this will help make sure there's no question. If we're not
in multifunction mode the partition_id will always be 1.

Previously we were only checking if the link up state had changed,
and if it hadn't exiting the link event routine early. We should
also check if speed has changed, and if it has, stay and finish
processing the link event.

When in multi-function mode, e.g. Dell's NPAR, only partition 1
of each MAC is allowed to set WoL, speed, and flow control.

When in NPAR mode the driver instance might be controlling the base
partition or one of the other "fake" PFs. There are some things that
can only be done by the base partition, aka partition_id 1. This code
does a bit of work to find how many partitions are there per port and
what is the current partition_id.

These mac address already added by FCoE stack above netdev,
therefore adding them here is redundant.
