cfg80211: Pass station (extended) capability info to kernel

The information of the peer's capabilities and extended capabilities are
required for the driver to perform TDLS Peer UAPSD operations and off
channel operations. This information of the peer is passed from user space
using NL80211_CMD_SET_STATION command. This commit enhances
the function nl80211_set_station to pass the capability information of
the peer to the driver.

Similarly, there may be need for capability information for other modes,
so allow this to be provided with both add_station and change_station.

The information of the peer's capabilities is required for the driver
to perform TDLS Peer UAPSD operations. This information of the peer is
passed by the supplicant using NL80211_CMD_SET_STATION command. This
commit enhances the function nl80211_set_station to pass this

with the TDLS peer STA.

In addition, make the HT/VHT capability configuration handled more
consistently for other STA cases (reject both instead of just HT).

cfg80211: fix station change if TDLS isn't supported

Larry noticed (and bisected) that commit df881293c6ba9a12868491a717b25
"cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_station"
broke secure connections. This is is the case only for drivers that
don't support TDLS, where any kind of change, even just the change of
authorized flag that is required for normal operation, was rejected
now. To fix this, remove the checks. I have some patches that will add
proper verification for all the different cases later.

cfg80211/nl80211: add API for MAC address ACLs

Add API to enable drivers to implement MAC address based
access control in AP/P2P GO mode. Capable drivers advertise
this capability by setting the maximum number of MAC
addresses in such a list in wiphy->max_acl_mac_addrs.

An initial ACL may be given to the NL80211_CMD_START_AP
command and/or changed later with NL80211_CMD_SET_MAC_ACL.

Black- and whitelists are supported, but not simultaneously.

cfg80211: Allow TDLS peer AID to be configured for VHT

VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The
current design for TDLS is to first add a dummy STA entry before
completing TDLS Setup and then update information on this STA
entry based on what was received from the peer during the setup
exchange.

In theory, this could use NL80211_ATTR_STA_AID to set
the peer AID just like this is used in AP mode to set the AID
of an association station. However, existing cfg80211 validation
rules prevent this attribute from being used with set_station
operation. To avoid interoperability issues between different
kernel and user space version combinations, introduce a new
nl80211 attribute for the purpose of setting TDLS peer AID.
This attribute can be used in both the new_station and set_station
operations. It is not supposed to be allowed to change the AID
value during the lifetime of the STA entry, but that validation
is left for drivers to do in the change_station callback.

forced the driver to stop the AP mode.

When the driver is in P2P-Go mode, and when it goes thru automatic
recovery from firmware crashes, it uses this interface to notify the
userspace that the group has been deleted.
