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.

* 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.)

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.

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().

The IOMMU may stop processing page translations due to a perceived lack
of credits for writing upstream peripheral page service request (PPR)
or event logs. If the L2B miscellaneous clock gating feature is enabled
the IOMMU does not properly register credits after the log request has
completed, leading to a potential system hang.
BIOSes are supposed to disable L2B micellaneous clock gating by setting
L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This
patch corrects that for those which do not enable this workaround.

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

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.

Remove the function e1000e_commit_phy() and replace the few calls to it
with the same function pointer that it would call. The function pointer is
almost always set for the devices that access these code paths so there is
no risk of a NULL pointer dereference; for the few instances where the
function pointer might not be set (i.e. can be called for the few devices
which do not have this function pointer set), check for a valid function
pointer.

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:

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.

====================
this is a pull-request for net-next/master. There is are 9 patches by
Fabio Baltieri and Kurt Van Dijck which add LED infrastructure and
support for CAN devices. Bernd Krumboeck adds a driver for the USB CAN
adapter from 8 devices. Oliver Hartkopp improves the CAN gateway
functionality. There are 4 patches by me, which clean up the CAN's
Kconfig.

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.

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.

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.

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.
