170775232d ANQP: Add support to specify frequency in ANQP_GET command
Previously, wpa_supplicant fetched BSS channel info from scan results to
send ANQP Query frames. If the scan results for the specified BSS are
not available, the ANQP_GET command request was getting rejected.

Add support to send ANQP Query frame on the specified frequency without
requiring the scan results to be available.

The control interface command format:
- ANQP_GET <dst_addr> [freq=<freq in MHz>] <Query ID1>[,<Query ID2>,..]

2316cb358c MBO: Add option to add MBO query list to ANQP query
MBO techspec v0.0_r27 changed the MBO ANQP-element format. The MBO
element in ANQP query should now include an MBO Query List element that
contains a list of MBO elements to query.

Add API to add the MBO Query List to an ANQP query.

Format:
ANQP_GET <addr> <info_id>[,<info_id>]...[,mbo:<subtype>...]

Example for querying neighbor report with MBO cellular data
connection preference:
ANQP_GET <bssid> 272,mbo:2

8f47917493 MBO: Add support to send ANQP request to get cellular preference
This extends ANQP_GET command to support querying MBO cellular
preference also. The cellular preference can be requested along with
neigbor report by appending mbo:1 to the command arguments.

For example:
ANQP_GET <bssid> 272,mbo:1

f91a512f1f Add INTERWORKING_ADD_NETWORK command
This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.

INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

cf28c66bcb HS 2.0: Extend ANQP_GET to accept Hotspot 2.0 subtypes
This allows a single ANQP query to be used to fetch both IEEE 802.11
defined ANQP elements and Hotspot 2.0 vendor specific elements.

ANQP_GET <addr> <info id>[,<info id>]...
[,hs20:<subtype>][...,hs20:<subtype>]

For example:
ANQP_GET 00:11:22:33:44:55:66 258,268,hs20:3,hs20:4

aa26ba68b4 HS 2.0R2: Add tracking of provisioning SP
The new provisioning_sp cred field can now be used to track which SP
provisioned the credential. This makes it easier to find the matching
PPS MO from the management tree (./Wi-Fi/<provisioning_sp>).

4d5bda5fca Interworking: Add optional use of network selection on normal scans
auto_interworking=1 configuration parameter can be used to request
wpa_supplicant to use Interworking network selection automatically as a
part of the normal (non-Interworking) network selection if the scan
results do not match with enabled networks. This makes scanning work
similarly to the "interworking_select auto" command.

b1f122964e Add generic GAS request mechanism
The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or
with other (including vendor specific) advertisement protocols.

gas_request <BSSID> <AdvProtoID> [Query]
gas_response_get <addr> <dialog token> [offset,length]

For example, ANQP query for Capability list in interactive wpa_cli
session:

> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0
status_code=0 resp_len=32
> gas_response_get 02:00:00:00:01:00 00
01011c00010102010501070108010c01dddd0c00506f9a110200020304050607
> gas_response_get 02:00:00:00:01:00 00 0,10
01011c00010102010501
> gas_response_get 02:00:00:00:01:00 00 10,10
070108010c01dddd0c00
> gas_response_get 02:00:00:00:01:00 00 20,10
506f9a11020002030405
> gas_response_get 02:00:00:00:01:00 00 30,2
0607

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

b02fe7ff32 Interworking: Add commands for network selection
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.

afc064fe7a Interworking: Add ANQP query requests
Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.

New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.
