o Driver is doing memset with zero for total number of stats bytes when
it has already filled some data in the stats buffer, which can overwrite
memory area beyond the length of stats buffer.
o Fix this by initializing stats buffer with zero before filling any data in it.

AHB bus support was added in v2.6.38, through commit a0b907ee2a71
("ath5k: Add AHB bus support."). That code can only be build if the
Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been
added to the tree. So AHB bus support has always been dead code.
Let's remove all code that depends on ATHEROS_AR231X. If that symbol
ever gets added to the tree the AHB bus support can be re-added too.

Pull networking fixes from David Miller:
"Here is a quick pull request primarily meant to address the deconfig
fallout from changing SCSI_NETLINK from being used via 'select' to
being used via 'depends'.
I applied a set of 5 patches written by Michal Marek, and then I
carefully audited all of the remaining config files, basically:
1) I scanned every arch config file, and if it mentioned CONFIG_INET
or CONFIG_UNIX, I made sure it had CONFIG_NET=y
2) After that, I scanned every arch config file, and if it did not
have CONFIG_NET=y I made sure it did not reference any networking
config options.
Finally, we have some late breaking wireless fixes in here from John
Linville and co"

====================
pull request: wireless 2014-09-23
Please consider pulling this one last batch of fixes intended for the 3.17 stream!
For the NFC bits, Samuel says:
"Hopefully not too late for a handful of NFC fixes:
- 2 potential build failures for ST21NFCA and ST21NFCB, triggered by a
depmod dependenyc cycle.
- One potential buffer overflow in the microread driver."
On top of that...
Emil Goode provides a fix for a brcmfmac off-by-one regression which
was introduced in the 3.17 cycle.
Loic Poulain fixes a polarity mismatch for a variable assignment
inside of rfkill-gpio.
Wojciech Dubowik prevents a NULL pointer dereference in ath9k.

In the brcmf_count_20mhz_channels function we are looping through a list
of channels received from firmware. Since the index of the first channel
is 0 the condition leads to an off by one bug. This is causing us to hit
the WARN_ON_ONCE(1) calls in the brcmu_d11n_decchspec function, which is
how I discovered the bug.

This change adds support for the Linux PTP Hardware clock and timestamping
functionality provided by the hardware. There are actually two cases that
this timestamping is meant to support.
The first case would be an ordinary clock scenario. In this configuration
the host interface does not have access to BAR 4. However all of the host
interfaces should be locked into the same boundary clock region and as such
they are all on the same clock anyway. With this being the case they can
synchronize among themselves and only need to adjust the offset since they
are all on the same clock with the same frequency.
The second case is a boundary clock scenario. This is a special case and
would require both BAR 4 access, and a means of presenting a netdev per
boundary region. The current plan is to use DSA at some point in the
future to provide these interfaces, but the DSA portion is still under
development.

This change adds the messaging support needed to support PTP. In the case
of Tx timestamps it is necessary for the Switch Management entity to return
the frames via the mailbox as the host interface cannot know which port the
timestamp will be delivered to. In addition there is only one clock on the
entire switch, as such the entity that has BAR 4 access is the only one who
can actually update the frequency as it is the only one with access.

This patch adds limited debugfs support for the driver. Most of the
functionality needed for dumping registers is already provided via ethtool.
The only thing we saw that we really neeed was the ability to dump the
descriptor rings so as such this patch will add a fm10k directory containing a
listing of directories each one with a unique PCI Bus, Device, and Function
number. Each of those BDF directories will have a list of q_vectors, and
the q_vectors will contain a file for each of the Rx/Tx rings that are a part
of the vector. For example:
# ls -RD /sys/kernel/debug/fm10k/
/sys/kernel/debug/fm10k/:
0000:01:00.0
/sys/kernel/debug/fm10k/0000:01:00.0:

This patch adds support for management of the limited QOS features of the
FM10000 interface. Specifically we can support up to 8 traffic classes,
however the part only provides 1 Rx and 1 Tx FIFO in the host interface and
as a result this can lead to head-of-line blocking on Rx. This can be
avoided by setting PFC only for priorities that cannot afford to drop
frames.

This patch adds support for L2 MACVLAN by making use of the fact that the
RRC provides a unique tag per filter called a Global Resource Tag, or GLORT.
In the case of this offload what I have done is assigned a linear block of
these so that each GLORT represents one of the MACVLAN netdevs. By doing
this I can share the Rx queues and Tx queues for all of the MACVLAN netdevs
while allowing them to be demuxed in the Rx cleanup path.
