Previous implementation did not handle number of sequences correctly.
Make sure the iteration continues in both unicast and broadcast cases
until the five attempts have been made. In addition, improve timing by
checking 10 second time from the beginning of each iteration round and
not the last channel on which the Auth Req frame has been transmitted.

Previously, the Authentication Request frame was retried after 2+10 = 12
seconds since the wait for the response was not accounted for. Substract
that wait from the 10 second wait time to start the retries more quickly
based on the 10 second timer described in the tech spec.

This commit introduces the ACS functionality for the autonomous GO. The

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

While considering the movement of P2P GO from its current operating

Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
Previously, wpas_p2p_select_go_freq_no_pref() ended up selecting a 2.4
GHz band channel first before even considering 5 or 60 GHz channels.
This was likely done more or less by accident rather than by design when
the 5 GHz and 60 GHz band extensions were added. It seems reasonable to
enhance this by reordering the code to start with 5 and 60 GHz operating
classes and move to 2.4 GHz band only if no channel was available in 5
or 60 GHz bands for P2P GO use.
This does have some potential interop issues with 2.4 GHz only peer
devices when starting up an autonomous GO (i.e., without there being
prior knowledge of channels that the peers support). Upper layers are
expected to enforce 2.4 GHz selection if that is needed for some use
cases.
