mac80211: 802.11p OCB mode support
This patch adds 802.11p OCB (Outside the Context of a BSS) mode
support.
When communicating in OCB mode a mandatory wildcard BSSID
(48 '1' bits) is used.
The EDCA parameters handling function was changed to support
802.11p specific values.
The insertion of a newly discovered STAs is done in the similar way
as in the IBSS mode -- through the deferred insertion.
The OCB mode uses a periodic 'housekeeping task' for expiration of
disconnected STAs (in the similar manner as in the MESH mode).
New Kconfig option for verbose OCB debugging outputs is added.

mac80211: fix typo in starting baserate for rts_cts_rate_idx
It affects non-(V)HT rates and can lead to selecting an rts_cts rate
that is not a basic rate or way superior to the reference rate (ATM
rates[0] used for the 1st attempt of the protected frame data).
E.g, assuming drivers register growing (bitrate) sorted tables of
ieee80211_rate-s, having :
- rates[0].idx == d'2 and basic_rates == b'10100
will select rts_cts idx b'10011 & ~d'(BIT(2)-1), i.e. 1, likewise
- rates[0].idx == d'2 and basic_rates == b'10001
will select rts_cts idx b'10000
The first is not a basic rate and the second is > rates[0].
Also, wrt severity of the addressed misbehavior, ATM we only have one
rts_cts_rate_idx rather than one per rate table entry, so this idx might
still point to bitrates > rates[1..MAX_RATES].

Pull networking updates from David Miller:
"Most notable changes in here:
1) By far the biggest accomplishment, thanks to a large range of
contributors, is the addition of multi-send for transmit. This is
the result of discussions back in Chicago, and the hard work of
several individuals.
Now, when the ->ndo_start_xmit() method of a driver sees
skb->xmit_more as true, it can choose to defer the doorbell
telling the driver to start processing the new TX queue entires.
skb->xmit_more means that the generic networking is guaranteed to
call the driver immediately with another SKB to send.
There is logic added to the qdisc layer to dequeue multiple
packets at a time, and the handling mis-predicted offloads in
software is now done with no locks held.
Finally, pktgen is extended to have a "burst" parameter that can
be used to test a multi-send implementation.
Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
virtio_net
Adding support is almost trivial, so export more drivers to
support this optimization soon.
I want to thank, in no particular or implied order, Jesper
Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
David Tat, Hannes Frederic Sowa, and Rusty Russell.
2) PTP and timestamping support in bnx2x, from Michal Kalderon.
3) Allow adjusting the rx_copybreak threshold for a driver via
ethtool, and add rx_copybreak support to enic driver. From
Govindarajulu Varadarajan.
4) Significant enhancements to the generic PHY layer and the bcm7xxx
driver in particular (EEE support, auto power down, etc.) from
Florian Fainelli.
5) Allow raw buffers to be used for flow dissection, allowing drivers
to determine the optimal "linear pull" size for devices that DMA
into pools of pages. The objective is to get exactly the
necessary amount of headers into the linear SKB area pre-pulled,
but no more. The new interface drivers use is eth_get_headlen().
From WANG Cong, with driver conversions (several had their own
by-hand duplicated implementations) by Alexander Duyck and Eric

6) Support checksumming more smoothly and efficiently for
encapsulations, and add "foo over UDP" facility. From Tom

7) Add Broadcom SF2 switch driver to DSA layer, from Florian
Fainelli.
8) eBPF now can load programs via a system call and has an extensive
testsuite. Alexei Starovoitov and Daniel Borkmann.
9) Major overhaul of the packet scheduler to use RCU in several major
areas such as the classifiers and rate estimators. From John
Fastabend.
10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
Duyck.
11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric

12) Add Datacenter TCP congestion control algorithm support, From

"This time around, the cleanup branch contains mostly code removal. A
number of board files for at91, imx and msm have become obsolete
because of the DT conversion and are now ready to be removed. The
OMAP platform has traditionally had its own DMA engine abstraction and
as this is being phased out, a lot of the original code is now unused
and can be removed as well.
S3C24xx can be simplified now that the restart code is a proper device

Finally, a number of cleanups in shmobile are done to prepare for the
addition of new code in other branches"

cxgb4: clean up a type issue
The tx_desc struct holds 8 __be64 values. The original code in
ring_tx_db() took a tx_desc pointer then casted it to an int pointer and
then casted it to a u64 pointer. It was confusing and triggered some
static checker warnings.
I have changed the cxgb_pio_copy() function to only take tx_desc

was buggy to begin with.

net: fs_enet: Remove non NAPI RX and add NAPI for TX
When using a MPC8xx as a router, 'perf' shows a significant time spent in
fs_enet_interrupt() and fs_enet_start_xmit().
'perf annotate' shows that the time spent in fs_enet_start_xmit is indeed spent
between spin_unlock_irqrestore() and the following instruction, hence in
interrupt handling. This is due to the TX complete interrupt that fires after
each transmitted packet.
This patchset first remove all non NAPI handling as NAPI has become the only
mode for RX, then adds NAPI for handling TX complete.
This improves NAT TCP throughput by 21% on MPC885 with FEC.

r8169:add support for RTL8168EP
RTL8168EP is Realtek PCIe Gigabit Ethernet controller with DASH support.
It is a successor chip of RTL8168DP.
For RTL8168EP, the read/write ocp register is via eri channel type 2, so I
move ocp_xxx() related functions under rtl_eri_xxx. And use r8168dp_ocp_xxx()
for RTL8168DP ocp read/write, r8168ep_ocp_xxx() for RTL8168EP ocp read/write.
The way of checking dash enable is different with RTL8168DP. I use
r8168dp_check_dash()for RTL8168DP and r8168ep_check_dash() for RTL8168EP,
to check if dash is enabled.
The driver_start() and driver_stop() of RTL8168EP is also different with
RTL8168DP. I use rtl8168dp_driver_xxx() for RTL8168DP and
rtl8168ep_driver_xxx for RTL8168EP.
Right now, RTL8168EP phy mcu did not need firmware code patch, so I did not

Pull staging updates from Greg KH:
"Here is the big staging patch set for 3.18-rc1.
Once again, we are deleting more code than we added, with something
like 150000 lines deleted overall. Some of this is due to drivers
being added to the networking tree, so the old versions are removed
here, but even then, the overall difference is quite good.
Other than driver deletions, lots and lots and lots of minor cleanups
all over the place. Full details are in the changelog"
