"This is the first NFC pull request for 3.14

It includes:

* A new NFC driver for Marvell's 8897, and a few NCI fixes and
  improvements needed to support this chipset.

* An LLCP fix for how we were setting the default MIU on a p2p link. If
  there is no explicit MIU extension announced at connection time, we
  must use the default one and not the one announced at LLCP link
  establishement time.

* A pn544 EEPROM config update. Some of the currently EEPROM configured
  values are overwriting the firmware ones while other should not be set
  by the driver itself.

* Some NFC digital stack fixes and improvements. Asynchronous functions
  are better documented, RF technologies and CRC functions are set upon
  PSL_REQ reception, and a few minor bugs are fixed.

* Minor and miscelaneous pn533, mei_phy and port100 fixes."

Add set_bitrate_mask callback. Currently
ath10k HW is limited to handle only single
fixed rate setting or limit number of used
spatial streams.

Example:
iw wlanX set bitrates legacy-5 ht-mcs-5 vht-mcs-5 2:9
will setup VHT, nss=2, mcs=9

iw wlanX set bitrates legacy-5 18 ht-mcs-5 vht-mcs-5
will setup legacy, 18Mbps

iw wlanX set bitrates legacy-5 ht-mcs-5 3 vht-mcs-5
will setup HT, nss=1, mcs=3

iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9
will setup nss=1

iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9 2:0-9
will setup nss=2

AR9462 recently, but this is causing baseband issues.
Disable it until this feature is tested well. Also,
remove the feature bit for AR9565 since it is

Accessing the current channel definition in mac80211
when processing RX packets is problematic because it
could have been updated when a scan is issued. Since a
channel change involves flushing the existing packets
in the RX queue before a chip-reset is done, they would
be processed using the wrong band/channel information.

To avoid this, use the current channel information
maintained in the driver.

The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

With a dissasociated card I often encoutered very long scan delays.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

The curr_protocol field of nfc_digital_dev structure used to determine
if a target is currently active was set too soon, immediately when a
target is found. This is not good since there is no other way than
deactivate_target() to reset curr_protocol and if activate_target() is
not called, the target remains active and it's not possible to put the
device in poll mode anymore.

With this patch curr_protocol is set when nfc core activates a target,
puts a device up, or when an ATR_REQ is received in target mode.
