Bruce Allan c556d6072d e1000e: convert enums of register offsets and move #defines to regs.h
There are enough register offsets to warrant being in their own header
file, and doing so logically separates them from other header file content.
They have been converted from an enumerated data type to #defines as is
done in all the other Intel wired ethernet drivers.

Paul Gortmaker 7c1e7e99ab gianfar: dont conditionally alloc Rx/Err irq structs
Commit ee873fda3b

    "gianfar: Pack struct gfar_priv_grp into three cachelines"

causes the following null dereference at driver init on sbc8548:

   libphy: Freescale PowerQUICC MII Bus: probed
   Unable to handle kernel paging request for data at address 0x00000000
   Faulting instruction address: 0xc01d6a38
   Oops: Kernel access of bad area, sig: 11 [#1]
   [...]
   NIP [c01d6a38] gfar_parse_group+0x228/0x280
   LR [c01d6a34] gfar_parse_group+0x224/0x280
   Call Trace:
   [ef82dd60] [c01d6a34] gfar_parse_group+0x224/0x280 (unreliable)
   [ef82dd90] [c01d73a4] gfar_probe+0x284/0xfe0

The reason is that the commit also changed the allocation of the
Rx and error handling irq structs to be skipped for !MQ_MG_MODE.
In the !MQ_MG_MODE case, only the Tx irq struct is allocated.

Digging further, we see that MQ_MG_MODE is set only if we find
the OF compatible string "fsl,etsec2".

A quick grep in the dts directory shows lots of boards that support
Rx/Tx/Err, but without this specific compat string.  And hence they
go after the unallocated Rx/Error structs and cause the above oops.

Hence such a change can not be deployed until all the dts files
are updated and sufficiently deployed.  Further, the optimization
is of limited value, since the kmalloc'd struct in question has only
a single unsigned int, and an (IFNAMSIZ + 6) sized string.

Note that no changes to the freeing code are needed here, as it
already did an unconditional free of Rx/Tx/Error gfar_irqinfo.

Arend van Spriel 7b2385b953 brcmsmac: rework of mac80211 .flush() callback operation
This patch addresses a long standing issue of the driver with the
mac80211 .flush() callback. Since implementing the .flush() callback
a number of issues have been fixed, but a WARN_ON_ONCE() was still
triggered because the timeout on the flush could still occur.

This patch changes the awkward design using msleep() into one using
a waitqueue. The waiting flush() context will kick the transmit dma
when it is idle and the timeout used waiting for the event is set
to 500 ms. Worst case there can be 64 frames outstanding for transmit
in the driver. At a rate of 1Mbps that would take 1.5 seconds assuming
MTU is 1500 bytes and ignoring retries. The WARN_ON_ONCE() is also
removed as this was put in to indicate the flush timeout as a reason
for the driver to stall. That was not happening since fixing endless
AMPDU retries with following upstream commit:

Larry Finger a5ffbe0a19 rtlwifi: Fix scheduling while atomic bug
Kernel commits 41affd5 and 6539306 changed the locking in rtl_lps_leave()
from a spinlock to a mutex by doing the calls indirectly from a work queue
to reduce the time that interrupts were disabled. This change was fine for
most systems; however a scheduling while atomic bug was reported in
https://bugzilla.redhat.com/show_bug.cgi?id=903881. The backtrace indicates
that routine rtl_is_special(), which calls rtl_lps_leave() in three places
was entered in atomic context. These direct calls are replaced by putting a
request on the appropriate work queue.

Currently, when the PF driver is unloaded and re-loaded while VFs are attached

The PF driver now uses the newly defined/created GET_IFACE_LIST cmd

(enabled in its previous life). The PF driver then uses the if_id for
further VF configuration.

query pmac-ids used by its VFs.

Bjørn Mork bf414b369f net: usbnet: fix tx_dropped statistics
It is normal for minidrivers accumulating frames to return NULL
from their tx_fixup function. We do not want to count this as a
drop, or log any debug messages.  A different exit path is
therefore chosen for such drivers, skipping the debug message
and the tx_dropped increment.

The test for accumulating drivers was however completely bogus,
making the exit path selection depend on whether the user had
enabled tx_err logging or not. This would arbitrarily mess up
accounting for both accumulating and non-accumulating minidrivers,
and would result in unwanted debug messages for the accumulating
drivers.

Fix by testing for FLAG_MULTI_PACKET instead, which probably was
the intention from the beginning.  This usage match the documented
behaviour of this flag:

 Indicates to usbnet, that USB driver accumulates multiple IP packets.

David S. Miller 33397a7121 Merge branch 'delete-wanrouter' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Paul Gortmaker says:

====================
The removal of wanrouter code was originally listed in the (now
gone) feature removal file since May 2012, and an RFC of the
deletion was posted[1] in late 2012.  The overall concept was given
an OK, but defconfig contamination, build failures, etc. meant that
it didn't quite make it into mainline for 3.8.

Since that time, Dan discovered (via code audit) a runtime bug that
proves nobody has been using this for over four years[2].  With that
new information, I think it makes sense for someone to follow through
on Joe's original RFC and get this done for the 3.9 release.

In addition to resolving the build failures of the RFC by keeping
stub headers, this also splits the change into two parts, just like
the token ring removal did.  Part #1 decouples the mainline kernel
from the expired subsystem, and part #2 does the large scale
deletion of the subsystem content.

The advantage of the above, is that a "git blame" will never lead
you to a 4000+ line deletion commit.  The large scale deletion will
never show up in a "git blame" and hence the same advantages that we
get from the "--irreversible-delete" in the review stage of "git
format-patch" are also embedded into the git history itself.  This
may seem like a moot point to some, but for those who spend a
considerable amount of time data mining in the git history, this is
probably worth doing.

I have done build tests of all[mod/yes]config for both the stage 1
(Makefile and Kconfig) and stage 2 (full driver delete) as a sanity
check, and the issues with the previously posted RFC should be gone.

Speaking of "--irreversible-delete" -- these patches were created
with that option, so if you want to use them locally, you are going
to have to pull (location below) the content instead of doing a
"git am" of the mailed out content.

We actually store the MAC address as well as the board_name here.  The
longest board_name is 75 characters so there is more than enough room
to hold the 17 character MAC and the ": " divider.  But making this

potentially it could happen with any other interfaces as well.

The tx buffer reconfiguration is not really useful in firmware.

Paul Gortmaker 6fcdf4facb wanrouter: delete now orphaned header content, files/drivers
The wanrouter support was identified earlier as unused for years,
and so the previous commit totally decoupled it from the kernel,
leaving the related wanrouter files present, but totally inert.

Here we take the final step in that cleanup, by doing a wholesale
removal of these files.  The two step process is used so that the
large deletion is decoupled from the git history of files that we
still care about.

The drivers deleted here all were dependent on the Kconfig setting
CONFIG_WAN_ROUTER_DRIVERS.

A stub wanrouter.h header (kernel & uapi) are left behind so that
drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that
we don't accidentally break userspace that expected these defines.

("net/wanrouter: Deprecate and schedule for removal") in May 2012.

More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39 ("netdevice wanrouter: Convert directly reference of
netdev->priv").  So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.

This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.

Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Amir Vadai 3484aac161 net/mlx4_en: Fix transmit timeout when driver restarts port
Under heavy CPU load, changing, ring size/mtu/etc. could result in transmit
timeout, since stop-start port might take more than 10 seconds.
Calling netif_detach_device to prevent tx queue transmit timeout.

netif_detach_device() is not called under ndo_stop, because netif_carrier_off
will prevent the timeout, and device should not be marked as not present, or
else user won't be able to start it later on.

Hadar Hen Zion 23537b732f net/mlx4_core: Use firmware driven flow steering hash mode
The Firmware dynamically changes flow steering hash configuration from covering
L2 only to "full" L2/L3/L4 mode needed.  The dynamic change allows the driver
to set hard coded hash configuration which is changed by the firmware from L2
to L2/L3/L4 when attaching the first L3/L4 flow steering rule and back to L2
when there are no more such rules.

Makes more sense to have randomly generated address by default than to

Also note that this changes only behaviour of bonds with no slaves. Once

here).

Also, fix dev_assign_type values on the way.

Sven Eckelmann 4ab0b0aa57 ath9k: Update spectral scan output data
The sample data received through the spectral scan can be either in big or
little endian byteorder. This information isn't stored in the output file.
Therefore it is not possible for the analyzer software to find the correct byte
order.

It is relative common to get the data from a low end AP in big endian mode and
transfer it to another computer in little endian mode to analyze it. Therefore,
it would be better to store it in network (big endian) byte order.

The extension of the 8 bit bins for each bin to 16 bit is not necessary. This
operation can be done in userspace or on a different machine. Instead the
max_exp defining the amount of shifting required for each bin is exported to
userspace.

The change of the output format requires a change of the type in the sample
tlv to allow the userspace program to correctly detect the bin format.

Simon Wunderlich 3a325565c7 ath9k: reorder error codes for spectral
When using the spectral scan feature, frames with phy errors are
returned for further processing to the driver. However, if the frames
also have an invalid CRC (which seems to happen quite often), the frame
is marked with bad CRC and not with the PHY error bit. The FFT
processing function will thus miss the frames.

Fix this by changing the precedence in error marking.

Bing Zhao 8a7d7cbf7b mwifiex: fix incomplete scan in case of IE parsing error
A scan request is split into multiple scan commands queued in
scan_pending_q. Each scan command will be sent to firmware and
its response is handlded one after another.

If any error is detected while parsing IE in command response
buffer the remaining data will be ignored and error is returned.

We should check if there is any more scan commands pending in
the queue before returning error. This ensures that we will call
cfg80211_scan_done if this is the last scan command, or send
next scan command in scan_pending_q to firmware.

Neil Horman 6cdd20c380 vmxnet3: set carrier state properly on probe
vmxnet3 fails to set netif_carrier_off on probe, meaning that when an interface
is opened the __LINK_STATE_NOCARRIER bit is already cleared, and so
/sys/class/net/<ifname>/operstate remains in the unknown state.  Correct this by
setting netif_carrier_off on probe, like other drivers do.

Also, while we're at it, lets remove the netif_carrier_ok checks from the
link_state_update function, as that check is atomically contained within the
netif_carrier_[on|off] functions anyway
