When a discovery request is received, add the peer to the TDLS peer
cache and send a response containing minimal data. Mandatory IEs in
the discovery response frame will be filled out by the driver.

Put glue code in place to propagate TDLS related driver capabilities to
the TDLS state machine.
If the driver doesn't support capabilities, assume TDLS is supported
internally.
When TDLS is explicitly not supported, disable all user facing TDLS
operations.

Allow passing high-level TDLS commands and TDLS frames to kernel
via new nl80211 commands.
Propagate TDLS related nl80211 capability flags from kernel and add them
as driver capability flags.

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.
Netlink sockets can be shared among all driver instances, saving lots
of sockets, spurious log messages, memory, and CPU usage when using
multiple interfaces in a single process.
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.
Some dualband cards can use more than five seconds to run through
a full scan, so increase the timeout to avoid hitting the missing
scan completed event workaround.
This fixes an issue where WPS run leaves a small ClientTimeout
value (2) configured and the next EAPOL authentication is started
with that small value even for Identity exchange. This can cause
problems when an EAPOL packet gets dropped immediately after
association and a retry of that packet is needed (which may take
more than two seconds).
This function can be used to clean up local UNIX domain socket files
that may be left over from clients that were previously connected to
wpa_supplicant. At least for now, this is only available for Android
builds.
