409cc1f8a4 bond: have random dev address by default instead of zeroes
Makes more sense to have randomly generated address by default than to
have all zeroes. It also allows user to for example put the bond into
bridge without need to have any slaves in it.

Also note that this changes only behaviour of bonds with no slaves. Once
the first slave device is enslaved, its address will be used (no change
here).

Also, fix dev_assign_type values on the way.

ee873fda3b gianfar: Pack struct gfar_priv_grp into three cachelines
* remove unused members(!): imask, ievent
* move space consuming interrupt name strings (int_name_* members) to
external structures, unessential for the driver's hot path
* keep high priority hot path data within the first 2 cache lines

This reduces struct gfar_priv_grp from 6 to 3 cache lines.
(Also fixed checkpatch warnings for the old code, in the process.)

0cd3fdea07 gianfar: Optimize struct gfar_priv_tx_q for two cache lines
Resize and regroup structure members to eliminate memory holes and
to pack the structure into 2 cache lines (from 3).
tx_ring_size was resized from 4 to 2 bytes and few members were re-grouped
in order to eliminate byte holes and achieve compactness.
Where possible, few members were grouped according to their usage and access
order (i.e. start_xmit vs. clean_tx_ring members), less important members
were pushed at the end.

John W. Linville says:

====================
Included is an NFC pull.  Samuel says:

"It brings the following goodies:

- LLCP socket timestamping (To be used e.g with the recently released nfctool
  application for a more efficient skb timestamping when sniffing).
- A pretty big pn533 rework from Waldemar, preparing the driver to support
  more flavours of pn533 based devices.
- HCI changes from Eric in preparation for the microread driver support.
- Some LLCP memory leak fixes, cleanups and slight improvements.
- pn544 and nfcwilink move to the devm_kzalloc API.
- An initial Secure Element (SE) API.
- An nfc.h license change from the original author, allowing non GPL
  application code to safely include it."

Also included are a pair of mac80211 pulls.  Johannes says:

"We found two bugs in the previous code, so I'm sending you a pull
request again this soon.

This contains two regulatory bug fixes, some of Thomas's hwsim beacon
timer work and a documentation fix from Bob."

"Another pull request for mac80211-next. This time, I have a number of
things, the patches are mostly self-explanatory. There are a few fixes
from Felix and myself, and random cleanups & improvements. The biggest
thing is the partial patchset from Marco preparing for mesh powersave."

Additionally, there are a pair of iwlwifi pulls.  Johannes says:

"For iwlwifi-next, I have a few cleanups/improvements as well as a few
not very important fixes and more preparations for new devices."

"Please pull a few updates for iwlwifi. These are just some cleanups and
a debug improvement."

On top of that, there is a slew of driver updates.  This includes
brcmfmac, mwifiex, ath9k, carl9170, and mwl8k as well as a handful
of others.  The bcma and ssb busses get some attention as well.
Still, I don't see any big headliners here.

Also included is a pull of the wireless tree, in order to resolve
some merge conflicts.

8a67b05db9 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
Jeff Kirsher says:

====================
This series contains updates to e1000e, ixgbevf, igb and igbvf.
Majority of the patches are code cleanups of e1000e where code
is removed (Yeah!).  The other two e1000e patches are fixes.  The
first is to fix the maximum frame size for 82579 devices.  The second
fix is to resolve an issue with devices other than 82579 that suffer
from dropped transactions on platforms with deep C-states when
jumbo frames are enabled.

The ixgbevf patch is to ensure that the driver fetches the correct,
refreshed value for link status and speed when the values have changed.

The igb and igbvf patches are a solution to an issue Stefan Assmann
reported, where when the PF is up and igbvf is loaded, the MAC address
is not generated using eth_hw_addr_random().

8d56b6d507 igbvf: be sane about random MAC addresses
Tighten up some of the code surrounding MAC addresses. Since the PF is
now giving all zeros instead of a random address, check for this case
and generate a random address. This ensures that we always know when we
have a random address and udev won't get upset about it.

Additionally, tighten up some of the log messages and clean up the
formatting.

3e35d9918c e1000e: adjust PM QoS request
It has been found that devices other than 82579 (a.k.a. e1000_pch2lan)
suffer from dropped transactions on platforms with deep C-states when
jumbo frames are enabled.  For example, LOMs on ICH9- and ICH10-based
platforms which recently had early-receive de-featured (for stability
reasons) suffer from this.  To resolve this for all devices, when jumbo
frames are enabled set the PM QoS DMA latency request based on the size
of the receive packet buffer less one full frame.

cef401de7b net: fix possible wrong checksum generation
Pravin Shelar mentioned that GSO could potentially generate
wrong TX checksum if skb has fragments that are overwritten
by the user between the checksum computation and transmit.

He suggested to linearize skbs but this extra copy can be
avoided for normal tcp skbs cooked by tcp_sendmsg().

This patch introduces a new SKB_GSO_SHARED_FRAG flag, set
in skb_shinfo(skb)->gso_type if at least one frag can be
modified by the user.

Typical sources of such possible overwrites are {vm}splice(),
sendfile(), and macvtap/tun/virtio_net drivers.

Tested:

$ netperf -H 7.7.8.84

Performance of the SENDFILE is impacted by the extra allocation and
copy, and because we use order-0 pages, while the TCP_STREAM uses
bigger pages.

6642f91c92 dm9601: support dm9620 variant
dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum
offload, ..), but it can also be put in a dm9601 compatible mode, allowing
us to reuse the existing driver.

This does mean that the extended features like checksum offload cannot be
used, but that's hardly critical on a 100mbps interface.

Thanks to Sławek Wernikowski <slawek@wernikowski.net> for providing me
with a dm9620 based device to test.

78fb2de711 net/mlx4_en: Initialize RFS filters lock and list in init_netdev
filters_lock might have been used while it was re-initialized.
Moved filters_lock and filters_list initialization to init_netdev instead of
alloc_resources which is called every time the device is configured.

7225922558 net/mlx4_en: Fix a race when closing TX queue
There is a possible race where the TX completion handler can clean the
entire TX queue between the decision that the queue is full and actually
closing it. To avoid this situation, check again if the queue is really
full, if not, reopen the transmit and continue with sending the packet.

f356fcbe12 net/mlx4_core: Return proper error code when __mlx4_add_one fails
Returning 0 (success) when in fact we are aborting the load, leads to kernel
panic when unloading the module. Fix that by returning the actual error code.

db0e7cba6d net/mlx4_en: Fix traffic loss under promiscuous mode
When port is stopped and flow steering mode is not device managed: promisc QP
rule wasn't removed from MCG table.
Added code to remove it in all flow steering modes.
In addition, promsic rule removal should be in stop port and not in start
port - moved it accordingly.

b4a496319f net: phy: icplus: Use the RGMII interface mode to configure clock delays
Like several other PHY devices which support RGMII, the IC+1001 allows
additional delays to by added to the RX_CLK and TX_CLK signals to
compensate for skew between the clock and data signals. Previously this
was always enabled, but this change makes use of the different RGMII
interface modes to allow the user to specify whether this should be
enabled.

commit 9992c2e (net: cdc_ncm: workaround for missing CDC Union)
added code to lookup an IAD for the interface we are probing.
This is redundant.  The USB core has already done the lookup
and saved the result in the USB interface struct.  Use that
instead.
