If the kernel supports this, don't use manual null

The non-monitor TX currently uses a normal L2 abstraction
socket, but that will also receive frames we don't want,
so use a plain socket that isn't bound for RX. This might
be possible using the L2 abstraction, but we need a plain
socket later for getting TX status events here.

This changes the auto-detection of whether or not the device contains

that ath6kl isn't broken right away.

The source code compiles into different objects depending on
the contents of .config. Therefore, the objects should depend
on .config.
Previously, only the executables depended on .config. This meant
that they were re-linked when .config changed. But that relink
process used the old (and now wrong) objects.
This patch implements shared_freq handler for driver_nl80211.c. If a
"p2p_group_add" happens after legacy STA association, then this patch
will help to start the GO on the same frequency. This is useful when
supplicant is started on multiple interface running over a singly "PHY"
and the station interface is not used for the P2P device operations.
For example, wpa_supplicant -iwlan0 .. -N -iwlan1 ... and wlan0 is used
for station connection and wlan1 as the P2P device interface.

When GO negotation fails the WPS method is currently not cleared, which
can result in GO negotiation being resumed when a GO negotiation request
frame is received from the peer. That is unexpected as locally we
already gave up.
This manifests itself in getting

Clear the WPS method to avoid this situation. I wasn't

assume this is how the situation happened.

If P2P device expires while a GO Negotiation is in progress, currently
p2p->go_neg_peer is cleared without indicating GO Nego failure. This
will result in pending group interfaces to be left over. This patch will
indicate GO Negotiation failure and will remove any pending group
interfaces.
This patch addresses a corner case in GO-Negotiation case. Consider the
scenario where two devices A and B are in discovery stage and Device B
vanishes [moves out of range] when a connect is issued on the Device A.
Then Device A keeps on retrying the GO Negotiation Request till the
retry limit is reached. On reaching retry limit, the pending group
interface is removed. But suppose if the peer entry in the device list
expires before the retry limit is reached, then pending group interface
was not removed.

Scan wasn't initiated in case the config contained only networks without

to actively scan but include all the SSIDs in the filter list. Also
added some debug logs to easily see which SSIDs were included in which
list.

If a P2P client associates with the group while it is
already associated, two member entries may be added to
the group which also confuses num_members counting.
Deal with this by removing the existing entry first
before adding a new one.
I think the way Reinette ran into this was due to our
tx_sync implementation in iwlagn, mac80211 might have
queued two association frames thinking the first one
just failed, but both only went out after the sync was
really successful (which tx_sync doesn't wait for).

Use a temporary PTK buffer during 4-way handshake when rekeying PTK
so that the new EAPOL-Key frame MIC values are checked against the
new PTK and frames are decrypted using the old PTK. Take the new
PTK into use once msg 4/4 is processed and clear RSC counters at
that point (including moving of RSC update to avoid setting RSC
based on the msg 4/4).
In addition, add a workaround to handle supplicant implementations that
set Secure bit to one during PTK rekeying 4-way handshake in msg 2/4.
This was previously assumed to be msg 4/4, but the key data contents
can be used to figure out whether this is msg 2/4 even if the Secure
bit is set to one.
