Johannes Berg dd840f793c AP: Add explicit EAPOL TX status event
The new event can be used when EAPOL TX status can't be reported as a
complete 802.11 frame but is instead reported as just the EAPOL data as
originally passed to hapd_send_eapol().

Jithu Jance 57ebba598d nl80211: Implement shared_freq
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.

Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
with MSVC was the only reason for having to maintain the same order
of function pointers in struct wpa_driver_ops and for having to
update driver_ndis.c for all changes in that structure.

In scan.c, merge a channel's noise value into the scan results. When
comparing scan results, compute the signal-to-noise ratio and use it
when available. Prefer a 5 GHz network if its SNR is really big (> 30)
or if its SNR is relatively close to the other network's.

Jouni Malinen b3af99d202 nl80211: Disable IEEE 802.11b rates only for P2P iftypes
Instead of hardcoding IEEE 802.11b rates to be disabled whenever
P2P support is built in and supported by the driver, do this only
when an interface is set to P2P mode (both when adding a new
interface and when changing the interface mode). This re-enables
use of IEEE 802.11b APs with CONFIG_P2P=y builds.

Jouni Malinen 97bcd562eb Remove disable_11b_rates() driver_ops
This function was used unconditionally if wpa_supplicant build
includes CONFIG_P2P=y. Adding a separate driver_ops for such use
is not really useful since the driver wrappers can do the same
internally. Remove this driver_ops and move matching functionality
into driver_nl80211.c which was the only driver wrapper using
this driver_ops callback.

Jouni Malinen 1dea5882be nl80211: Fix re-enabling of 802.11b rates
nl80211_disable_11b_rates() function was supposed to use the 'disabled'
parameter to figure out whether to disable or re-enable 802.11b rates.
In addition, the driver deinit path was now ending up re-disabling the
enabled rates at the end of the deinit operations when the interface
type was forced back to station. Both of these issues are now fixed
and the 2.4 GHz band TX rate index is cleared properly when
wpa_supplicant is stopped.

Jouni Malinen 59d249255c nl80211: Ignore netlink interface down if interface is up
The netlink event processing is delayed since they are only returned
after control returns to eloop. This can result in netlink down events
being processed at a point when the interface has is actually still
there (the first event on new interface is down) and that can result in
odd behavior especially when the resulting interface-disabled event is
delivered to AP mode interface with wpa_supplicant.

Work around this by filtering netlink down events if the matching
interface is up at the time the netlink event is processed. This fixes
an issue brought up by commit 36d84860bb.

Arik Nemtsov 45b722f150 TDLS: Add peer as a STA during link setup
Before commencing setup, add a new STA entry to the driver representing
the peer. Later during setup, update the STA entry using information
received from the peer.

Extend sta_add() callback for adding/modifying a TDLS peer entry and

nl80211 driver and send peer information to kernel.

Mark TDLS peer entries with a new flag and translate it to a
corresponding nl80211 flag in the nl80211 driver.

In addition, correct TDLS related documentation in the wpa_driver_ops
structure.
