Jouni Malinen 4ec833daf8 Extend hmac_sha256_kdf() to support HKDF-Expand() as defined in RFC 5869
The KDF define in RFC 5295 is very similar to HKDF-Expand() defined in
RFC 5869. Allow a NULL label to be used to select the RFC 5869 version
with arbitrary seed (info in RFC 5869) material without forcing the
label and NULL termination to be included. HKDF-Expand() will be needed
for OWE.

Vasanthakumar Thiagarajan 7cbb5f1a44 DFS: Handle pre-CAC expired event
As FCC DFS requirement does not explicitly mention about the validity of
the (pre-)CAC when channel is switched, it is safe to assume that the
pre-CAC result will not be valid once the CAC completed channel is
switched or radar detection is not active on the (CAC completed) channel
within a time period which is allowed (10 seconds - channel switch time)
as per FCC DFS requirement.

Use the new driver event to allow the driver to notify expiry of the CAC
result on a channel. Move the DFS state of the channel to 'usable' when
processing pre-CAC expired event.  This means any future operation on
that channel will require a new CAC to be completed. This event is
applicable only when DFS is not offloaded to the kernel driver.

Vasanthakumar Thiagarajan 3dcd735c1e DFS: Handle CAC completion event from other radio
When DFS channel state is shared across multiple radios on the system it
is possible that a CAC completion event is propagated from other radio
to us. When in enabled state, do not proceed with setup completion upon
processing CAC completion event with devices where DFS is not offloaded,
when in state other than enabled make sure the configured DFS channel is
in available state before start the AP.

The userspace may want to delay the the first scheduled scan.
This enhances sched_scan to add initial delay (in seconds) before
starting first scan cycle. The driver may optionally choose to
ignore this parameter and start immediately (or at any other time).

This uses NL80211_ATTR_SCHED_SCAN_DELAY to add this via user
