wlcore: fix occasional AP TX stop after recovery
The fw_status wasn't zeroed during allocation, resulting
in uninitialized var usage, and finally causing AP
traffic stop after recovery.
The wrong value in fw_status_2->counters.tx_lnk_free_pkts
led to a bad lnk->allocated_pkts calculation in
wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return
FALSE (lnk->allocated_pkts > thold).

wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.
PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).
This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.
The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.
The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:
1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

Merge tag 'nfc-next-3.11-1' of git://git./linux/kernel/git/sameo/nfc-next
Samuel Ortiz <sameo@linux.intel.com> says:
"These are the pending NFC patches for the 3.11 merge window.
It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2),
along with a few more for the pn544 and pn533 drivers, the LLCP
disconnection path and an LLCP memory leak.
Highlights for this one are:
- An initial secure element API. NFC chipsets can carry an embedded
secure element or get access to the SIM one. In both cases they
control the secure elements and this API provides a way to discover,
enable and disable the available SEs. It also exports that to
userspace in order for SE focused middleware to actually do something
with them (e.g. payments).
- NCI over SPI support. SPI is the most complex NCI specified transport
layer and we now have support for it in the kernel. The next step will
be to implement drivers for NCI chipsets using this transport like
e.g. bcm2079x.
- NFC p2p hardware simulation driver. We now have an nfcsim driver that
is mostly a loopback device between 2 NFC interfaces. It also
implements the rest of the NFC core API like polling and target
detection. This driver, with neard running on top of it, allows us to
completely test the LLCP, SNEP and Handover implementation without
physical hardware.
- A Firmware update netlink API. Most (All ?) HCI chipsets have a
special firmware update mode where applications can push a new
firmware that will be flashed. We now have a netlink API for providing
that mode to e.g. nfctool."

ath9k: Fix noisefloor calibration
The commits,
"ath9k: Fix regression in channelwidth switch at the same channel"
"ath9k: Fix invalid noisefloor reading due to channel update"
attempted to fix noisefloor calibration when a channel switch
happens due to HT20/HT40 bandwidth change. This is causing invalid
readings resulting in messages like:
"ath: phy16: NF[0] (-45) > MAX (-95), correcting to MAX".
This results in an incorrect noise being used initially for reporting
the signal level of received packets, until NF calibration is done
and the history buffer is updated via the ANI timer, which happens
much later.
When a bandwidth change happens, it is appropriate to reset
the internal history data for the channel. Do this correctly in the
reset() routine by checking the "chanmode" variable.

brcmfmac: Signalling header push and pull on logic places.
Currently suppressed packets get enque-ed with header which
then gets pulled before transmit. It is more logical and clean
to pull the header on return and push it unconditionally on xmit.

brcmfmac: Accept only first creditmap event.
During P2P testing it turned out that the firmware sents multiple
multiple creditmap event messages. Only the first message from the
firmware should be processed. Otherwise the firmware-signalled flow
control can run haywire when it has packets outstanding in firmware.

brcmfmac: fix invalid ifp lookup in firmware-signalling
The destination entries for firmware-signalled flow control have
the interface id stored. This needs to be translated to bsscfg
index when looking up the ifp object for the interface.

brcmfmac: Find correct MAC descriptor in case of TDLS.
In case of TDLS find the correct MAC descriptor for fw signalling
data. In case of TDLS each destination gets its own entry. This
was not handled correctly for P2P client.
