When a mesh link is in blocked state, it is very useful to still allow
auth requests from the peer to re-establish it.
When a remote node is power cycled, the peer state can easily end up
in blocked state if multiple auth attempts are performed. Since this
can lead to several minutes of downtime, we should accept auth attempts
of the peer after it has come back.

Add a flag attribute to use in ap settings to indicate userspace
supports offloading of SA Query procedures to driver. Also add AP SME
device feature flag to advertise that the SA Query procedures offloaded
to driver when userspace indicates support for offloading of SA Query
procedures.

Driver handles SA Query procedures in driver's SME it self and skip
sending SA Query request or response frames to userspace when userspace
indicates support for SA Query procedures offload. But if userspace
doesn't advertise support for SA Query procedures offload driver shall
not offload SA Query procedures handling.

Also userspace with SA Query procedures offload capability shall skip SA
Query specific validations when driver indicates support for handling SA
Query procedures.

Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time

NL80211_CMD_SET_SAR_SPECS is added to configure SAR from
user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR
power specification when used with NL80211_CMD_SET_SAR_SPECS.

Wireless driver needs to register SAR type, supported frequency
ranges to wiphy, so user space can query it. The index in
frequency range is used to specify which sub band the power
limitation applies to. The SAR type is for compatibility, so later
other SAR mechanism can be implemented without breaking the user
space SAR applications.

Normal process is user space queries the SAR capability, and
gets the index of supported frequency ranges and associates the
power limitation with this index and sends to kernel.

Here is an example of message send to kernel:

The CMD_PORT_AUTHORIZED event was described as an event which indicated
a successfully completed 4-way handshake. But the behavior was
not as advertized. The only driver which uses this is brcmfmac, and
this driver only sends the event after a successful 802.1X-FT roam.

This prevents userspace applications from knowing if the 4-way completed
on:

1. Normal 802.1X connects
2. Normal PSK connections
3. FT-PSK roams

wpa_supplicant handles this incorrect behavior by just completing
the connection after association, before the 4-way has completed.
If the 4-way ends up failing it disconnects at that point.

Since this behavior appears to be expected (wpa_s handles it this
way) I have changed the wording in the API description to reflect the
actual behavior.

Let drivers advertise support for AP-mode WPA/WPA2-PSK 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_AP_PSK flag.

Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_START_AP command, and contain the PSK (which is
the PMK, hence the name).

The driver is assumed to handle the 4-way handshake by itself in this
case, instead of relying on userspace.

Add a new feature flag that drivers can use to advertize support for
Operating Channel Validation (OCV) when using driver's SME for RSNA
handshakes.
