This makes it easier to write hwsim test cases to verify management
frame processing sequences with dropped or modified frames. When
ext_mgmt_frame_handling is used, this new command can be used to request
hostapd to process a received a management frame, e.g., based on
information reported in the MGMT-RX events.
This is more or less identical to the earlier wpa_supplicant commit
4de70e2330 ('Add MGMT_RX_PROCESS test
command for wpa_supplicant'), but for hostapd.

Commit 4ec1fd8e42 ('FT: Differentiate
between FT for station and for AP in build') renamed all
CONFIG_IEEE80211R instances within src/ap/* to CONFIG_IEEE80211R_AP, but
it did not change hostapd/* files to match. While this does not cause
much harm for normal use cases, this broke some test builds where
wpa_supplicant build is used to build in hostapd/*.c files for analysis.
Fix this by completing CONFIG_IEEE80211R_AP renaming.

Add a configuration option in hostapd.conf and in neighbor report that
sets an AP as stationary. To enable this option on the current AP set
the config option stationary_ap to 1. To set a neighbor entry to be
marked as stationary add the word stat to the SET_NEIGHBOR command. This
option tells hostapd to send LCI data even if it is older than requested
by max age subelement in RRM request.

Implement the signature mechanism described in the paper
"Passive Taxonomy of Wifi Clients using MLME Frame Contents"
published by Denton Gentry and Avery Pennarun.
http://research.google.com/pubs/pub45429.htmlhttps://arxiv.org/abs/1608.01725
This involves:
1. Add a CONFIG_TAXONOMY compile option. Enabling taxonomy incurs
a memory overhead of up to several kilobytes per associated
station.
2. If enabled, store the Probe Request and (Re)Associate Request frame in
struct sta_info.
3. Implement code to extract the ID of each Information Element,
plus selected fields and bitmasks from certain IEs, into a
descriptive text string. This is done in a new source file,
src/ap/taxonomy.c.
4. Implement a "signature qq:rr:ss:tt:uu:vv" command
in hostapd_cli to retrieve the signature.
Signatures take the form of a text string. For example, a signature
for the Nexus 5X is:
wifi4|probe:0,1,127,45,191,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:338061b2,

Add FTM range request via RRM. The AP sends Radio measurement request
with FTM range request as a request for the receiving STA to send FTM
requests to the given list of APs. The neighbor report part of the
request is taken from the neighbor database.
The control interface command is:
REQ_RANGE <dst addr> <rand_int> <min_ap> <responder> [<responder>..]
dst addr: MAC address of an associated STA
rand_int: Randomization Interval (0..65535) in TUs
min_ap: Minimum AP Count (1..15); minimum number of requested FTM ranges
between the associated STA and the listed APs

The MBO IE includes the transition reason code, cellular data connection
preference, and, if the disassoc imminent bit is set, it may also
include re-association retry delay. Otherwise, the re-association retry
delay should be set to zero.
The additional BSS_TM_REQ argument uses the following format:

Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.
The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.
New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.
When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.
To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.
Though not depended on by the code, vlan_id assignment ensures:
* vlan_id = 0 will continue to mean no AP_VLAN interface
* vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
with no per_sta_vif and no extra tagged vlan.
* vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.
This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.
DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.
MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.
Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).
Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

case of a dualband AP that operates concurrently on multiple bands under
the control of a single hostapd process.
