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.

ready to support non i2c physical layers.
- LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery

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.

when supporting connection less LLCP sockets.

This patch prepares mac80211 for a later implementation of mesh or
ad-hoc powersave clients.
The structures related to powersave (buffer, TIM map, counters) are
moved from the AP-specific interface structure to a generic structure
that can be embedded into any interface type.
The functions related to powersave are prepared to allow easy
extension with different interface types. For example with:
+ } else if (sta->sdata->vif.type == NL80211_IFTYPE_MESH_POINT) {
+ ps = &sdata->u.mesh.ps;
Some references to the AP's beacon structure are removed where they
were obviously not used.
The patch compiles without warning and has been briefly tested as AP
interface with one client in PS mode.

If the user wants to scan using a vif configured as AP,
cfg80211 must give him a chance to do it, even if this
will disrupt the stations performance due to off-channel
scanning. To do so, this patch adds a 'force' flag to the
SCAN_TRIGGER command which tells cfg80211 to perform the
scanning operation even if the vif is an AP and the
beaconing has already started.
