Commit 9f51b11395 added support for P2P
interfaces when adding a new interface. However, it didn't handle the
case in which the same interface is being used and its type is being
changed. Add support for this case.
Consequently, when doing "ap_scan_as_station" we now need to save the
actual AP interface type (AP/P2P GO) in order to restore it properly.
For that, change ap_scan_as_station type from int to nl80211_iftype, and
set it to NL80211_IFTYPE_UNSPECIFED when not used.

When driver_nl80211.c has to set the netdev down to change iftype, an
RTM_NEWLINK event is generated. Do not generate
EVENT_INTERFACE_DISABLED event based on that.
Only accept Probe Request frames that have a Wildcard BSSID and a
destination address that matches with our P2P Device Address or is the
broadcast address per P2P specification 3.1.2.1.1.
When a new interface is created and already has a separate MAC address
assigned by the kernel, then we need to use that address, not just when
we've created a locally administered address.
This fixes use_p2p_group_interface=1 for iwlagn as it already makes
mac80211 assign an address for a second interface since the hardware has
two addresses assigned.

Add support to wpa_supplicant for device-based GTK rekeying. In order to
support that, pass the KEK, KCK, and replay counter to the driver, and
handle rekey events that update the latter.

Send STA flags to kernel when adding a new station. This ensures
stations are added with up to date flags by kernel drivers.

When adding a new station, set the STA flags as part of the sta_add()
command. This ensures the flags are up to date when the station is added
by lower level drivers.

In set_key handler, the seq[8] is in little endian order defined by
WPA. BSD kernel uses a u_int64_t value ik_keyrsc to represent it
internally. The kernel expects the native endian order for the value.
Thus, we need to detect the endian order and swap bytes when
necessary.
Implement PMKSA cache operations add, remove, and flush using nl80211
commands NL80211_CMD_{SET,DEL,FLUSH}_PMKSA to support PMKSA caching
with drivers that select the AP and generate the RSN IE internally.
Some of these are required for proper functionality (like
get_seqnum); others may not be needed yet, but including them
allows some extra ifdef/endif blocks to be removed.
.set_rate_sets is not defined for non-hostapd, which prevents
configuring basic_rates when working as P2P GO.

cfg80211 maintains separate BSS table entries for APs if the same
BSSID,SSID pair is seen on multiple channels. wpa_supplicant does
not use frequency as a separate key in the BSS table, so filter out
duplicated entries. Prefer associated BSS entry in such a case in
order to get the correct frequency into the BSS table.
AF_INET6 is not always enabled by default, so use AF_INET instead. In
addition, use the old fixed length, 2048, as a failover value if the
sysctl fails for any reason.
When the SME is in the driver or cfg80211, the automatic selection
of auth_alg is done by leaving out the NL80211_ATTR_AUTH_TYPE
attribute from the NL80211_CMD_CONNECT command.
This should fix EAPOL reauthentication and rekeying timeout issues
with Intel clients when using WMM (e.g., with IEEE 802.11n). These
stations do not seem to be able to handle EAPOL data frames as
non-QoS Data frames after the initial setup.
This adds STA flags to hapd_send_eapol() driver op to allow
driver_nl80211.c to mark the EAPOL frames as QoS Data frame
when injecting it through the monitor interface.
This provides a means for the supplicant to directly request signal
quality metrics from the driver. This is useful, for example for
background scan algorithms that might ask desire this information
out-of-band with CQM events.

This allows driver wrappers to indicate whether the association was
done using Association Request/Response or with Reassociation
Request/Response frames.
The buffer size for routing socket is fixed to 2048.
This patch fix it to obtain the size from OS.
This patch worked on x86 platform with NetBSD 5.0.2.
The DBus code will want to have perfect matching of dev_found and the
dev_lost it adds so it doesn't need to keep track internally. Enable
that with a new flag in the core that tracks whether we have already
notified about this -- the existing users can ignore it.
The part where this is always set to 1 if the new device is discovered
by a driver that has P2P in the driver is buggy -- the driver should
feed the P2P peer database and then that should feed the notification
here instead.

This embeds some information about each P2P peer that will be publically
visible in a struct that is shared.
The dev_found notification function is also passed the new struct, which
requires some work for the driver-based P2P management.

If the driver advertises max_remain_on_chan data, use it instead of
the hardcoded value of 5000. Keep the default at 5000 since that is the
value used by earlier versions of cfg80211/mac80211 and not advertised
in nl80211 for those.
