Once the driver advertizes interface combination logic
based on its firmware/hardware limitation, cfg80211
takes care of all the necessary logic such as maximum
beaconing vifs, standlone interface etc.

When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight
(from STOMP_LOW) to provide more bandwidth for BT FTP profile.
WLAN's idleness can be estimated by taking into account of the
rx data packets and just ignore beacons, qos nullfunc etc.
Also update bt_wait_time even if the chip is in NETWORK SLEEP
mode. This should help BT throughput when WLAN is idle.

Several people have complained about an unusual
and undocumented feature of the AR9170 hardware:
In siffer mode, the hardware generates spurious
ACK frames for every received frame... even
broadcasts.
The reason for this malfunction is unknown:
<http://marc.info/?l=linux-wireless&m=134517238506033>
But there's a workaround: Instead of the special
sniffer mode, the hardware will be put into
station mode and all rx filters are disabled.

With this one we have:
- pn544 p2p support.
- pn544 physical and HCI layers separation. We are getting the pn544 driver
ready to support non i2c physical layers.
- LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery
protocol.
- LLCP datagram sockets (connection less) support.
- IDR library usage for NFC devices indexes assignement.
- NFC netlink extension for setting and getting LLCP link characteristics.
- Various code style fixes and cleanups spread over the pn533, LLCP, HCI and
pn544 code.

NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
a device. LTO must be set before the link is up otherwise -EINPROGRESS is
returned. RW and MIUX can be set at anytime and will be passed in subsequent
CONNECT and CC messages. If one of the passed parameters is wrong none is
set and -EINVAL is returned.

SNL (Service Name Lookup) allows for LLCP peers to map service names with
SAPs. This is mandatory for connection less support as peers need to get
the right SAPs without sending the CONNECT frame.
Here we only support the Rx part of SNL. The Tx one will be implemented
when supporting connection less LLCP sockets.
