4848a38d85 Get rid of duplicated cipher suite and AKM definitions
WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.

152cff6ba6 P2P: Remove WPA_DRIVER_FLAGS_P2P_MGMT option
The option of handling upper layer P2P management operations within the
driver/firmware was originally planned to be used with wpa_supplicant,
but this has not really happened and there is no clear sign of this
being needed in the near term either. This functionality has not been
completed and it is certainly not being kept up-to-date or tested. As
such, it is best to remove it for now and if this or something similar
is needed in the future, it can be brought back once a clear need for it
has been demonstrated first.

dbfb8e82ff Remove unnecessary EVENT_RX_ACTION
This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

2d2ecf51aa nl80211: Fix protected Action frame reporting for AP mode
Action frame RX report through EVENT_RX_ACTION did not indicate whether
the frame was protected or not even though that information is available
in mlme_event_mgmt(). hostapd_rx_action() has a workaround for setting
the protected flag for SA Query frames, but that did not apply for other
frames, like FT Action. This broke FT-over-DS when PMF is enabled with
newer kernel versions (i.e., the ones that do not use monitor interface
for receiving management frames).

acb69cec6f wpa_supplicant: Use monotonic time for RX/BSS times
The BSS table, scan timeout, and related functionality should use
monotonic time since they care about relative values (age) only.
Unfortunately, these are all connected, so the patch can't be split
further. Another problem with this is that it changes the driver wrapper
API. Though, it seems only the test driver is using this.

795baf773f hostapd: Filter channel list updated events after country code change
We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

f0793bf191 hostapd: Wait for channel list update after country code change
If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.
