Reporting skb->len to BQL just before exiting xmit is not correct
due to possible insertions of TOE block and alignment bytes in the
skb->data, which are being stripped off by the controller before
transmission on wire. This led to mismatch of (incorrectly)
reported bytes to BQL b/w xmit and Tx confirmation, resulting in
Tx timeout firing, for the h/w tx timestamping acceleration case.
There's no easy way to obtain the number of bytes on wire in the Tx

from xmit to Tx confirmation, for now (as proposed by Eric). Revived

and some code cleanup."
Also for mac80211:
"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."
And for iwlwifi:
"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."
Regarding the Bluetooth bits, Gustavo says:
"Patches to 3.12, here we have:
* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"
For the NFC bits, Samuel says:
"With this one we have:
- A few pn533 improvements and minor fixes. Testing our pn533 driver
against Google's NCI stack triggered a few issues that we fixed now.
We also added Tx fragmentation support to this driver.
- More NFC secure element handling. We added a GET_SE netlink command
for getting all the discovered secure elements, and we defined 2
additional secure element netlink event (transaction and connectivity).
We also fixed a couple of typos and copy-paste bugs from the secure
element handling code.
- Firmware download support for the pn544 driver. This chipset can enter a
special mode where it's waiting for firmware blobs to replace the
already flashed one. We now support that mode."
With repect to the ath tree, Kalle says:
"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.
For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."
I also pulled the wireless tree into wireless-next to support a
request from Johannes. On top of all that, there are the usual
sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.

ipv6: do not call ndisc_send_rs() with write lock
Because vxlan module will call ip6_dst_lookup() in TX path,
which will hold write lock. So we have to release this write lock
before calling ndisc_send_rs(), otherwise could deadlock.

ipv6: export a stub for IPv6 symbols used by vxlan
In case IPv6 is compiled as a module, introduce a stub
for ipv6_sock_mc_join and ipv6_sock_mc_drop etc.. It will be used
by vxlan module. Suggested by Ben.
This is an ugly but easy solution for now.

Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next
Ben Hutchings says:
====================
1. A little more refactoring.
2. Remove the unnecessary use of atomic_t that you pointed out.
3. Add support for starting or queueing firmware requests from atomic
context.
4. Add hwmon support for additional sensors found on some new boards.
5. Add support for the EF10 controller architecture, the SFC9100 family
and specifically the SFC9120 controller.

Multiqueue scheduler refers to default_qdisc_ops; therefore the
variable definition needs to be moved to handle case where net
scheduler API is not available.

By default, the pfifo_fast queue discipline has been used by default
for all devices. But we have better choices now.
This patch allow setting the default queueing discipline with sysctl.
This allows easy use of better queueing disciplines on all devices
without having to use tc qdisc scripts. It is intended to allow
an easy path for distributions to make fq_codel or sfq the default
qdisc.
This patch also makes pfifo_fast more of a first class qdisc, since
it is now possible to manually override the default and explicitly
use pfifo_fast. The behavior for systems who do not use the sysctl
is unchanged, they still get pfifo_fast
Also removes leftover random # in sysctl net core.

net/fec: cleanup types in fec_get_mac()
My static checker complains that on some arches unsigned longs can be 8
characters which is larger than the buffer is only 6 chars.
Additionally, Ben Hutchings points out that the buffer actually holds
big endian data and the buffer we are reading from is CPU endian.
