On P2P group removal, the GO is deinitialized correctly (and the vif
mode is set back to sta in case of nl80211), but the P2P client mode
wasn't deinitialized, and the nl80211 vif stays in P2P client mode.
Add a new deinit_p2p_cli op (similar to deinit_ap), which currently only
sets the interface back to station mode.

The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.
Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.
My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.

When drivers advertise their capability to free up inactive
stations based on ap_max_inactivity, send the inactivity period
timeout to driver in NL80211_ATTR_INACTIVITY_TIMEOUT. This
introduces a WPA_DRIVER_FLAGS (WPA_DRIVER_FLAGS_INACTIVITY_TIMER)
so that the inactivity period will be sent only when this capability
bit is set.

This allows HT capabilities overrides on kernels that

MCS Rates can be disabled to force to slower speeds when using HT.
Rates cannot be forced higher.
HT can be disabled, forcing an 802.11a/b/g/n station to act like

HT40 can be disabled.
MAX A-MSDU can be disabled.
A-MPDU Factor and A-MPDU Density can be modified.
Please note that these are suggestions to the kernel. Only mac80211
drivers will work at all. The A-MPDU Factor can only be decreased and
the A-MPDU Density can only be increased currently.

The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.
Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.

In some situations it might be benefical to send a unicast frame without

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.

This function is actually needed for quite a bit more than just
user space MLME implementation. The old comment here has not been
accurate for a long time, so get rid of it.
These driver_ops functions set_channel, set_ssid, set_bssid,
mlme_add_sta, and mlme_remove_sta were used with the user space
MLME implementation in wpa_supplicant. That was only for testing
purposes and was removed, but these driver_ops were forgotten.
Remove them now to remove confusing driver_ops definitions.
This code was used only with driver_test.c to allow MLME operations
in hostapd to be tested without having to use a real radio. There
are no plans on extending this to any other use than testing and
mac80211_hwsim has now obsoled the need for this type of testing.
As such, we can drop this code from wpa_supplicant to clean up the
implementation of unnecessary complexity.
This offloads the station polling to driver wrappers, which may offload
it again to the driver. The hostap driver wrapper uses "real" data
frames while nl80211 uses null data frames.
Also add a specific event to indicate that a poll was successful for
future use with the nl80211 driver.
Remove the separate driver_ops functions set_cts_protect(),
set_preamble(), set_short_slot_time(), and set_ht_params(). These
belong into same set of operations as set_ap(), so there is no need
to maintain separate functions that just make the driver wrapper
more complex.
Since these have only been used with driver_nl80211.c, the driver_ops
can be removed immediately instead of maintaining backwards
compatibility period with the old functions.
The AP client isolation parameter is now available through set_ap().
driver_nl80211.c was the only driver wrapper using the set_intra_bss()
call in hostap.git, but some external trees may have used this. Once
those are cleared, the set_infra_bss() driver_ops can be removed
completely. The only remaining use case for it currently is in P2P
GO mode with wpa_supplicant.
Pass SSIDs to be matched in scheduled scan results. Only the SSIDs
that are included in the match lists will be reported by the driver,
so the filtering can be offloaded to the hardware and the power
consumption can be reduced.

In new Linux kernel versions (>=3.0), nl80211 adds scheduled scan
capability. In order to use this feature to its full extent, we need
to support it in the wpa_supplicant core, so that it can also be used
by other drivers.
This commit adds initial scheduled scan support operations and events.

This new flag can be used to change wpa_supplicant behavior in the
default ap_scan=1 mode to move BSS selection into the driver (likely
firmware). This commit is only adding the flag; separate commits
will be used to change the actual connection/roaming behavior.
This allows drivers to disable CCK rates from Probe Request frames.
For nl80211, this is currently applying only to the supported rates
element(s), but this mechanism could be extended to address TX rate
control masking, too, to lessen need for global rate disabling.

The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().
