Previously, iwd used to throw net.connman.iwd.Busy when connection
attempt was made while connected. The new behavior allows iwd to
seamlessly disconnect from the connected network and attempt a new
connection.
Since NAI realms, Roaming Consortium and HESSID are defined in 802.11,
they are not a guarentee that the network is Hotspot 2.0. The indication
element in addition to these IE's gives a better idea of Hotspot 2.0
support. Now, when a BSS is added this is_hs20 boolean will get set to
true if the HS20 IE was found in the BSS.
Now, if is_hs20 is set AND one of NAI realms, roaming consortium, or
HESSID is set we know this is a hotspot 2.0 network.
Previously, on service disappeared event the list of the known
proxy objects was cleared, but pointers to the default entity
per command family wasn’t reset. Reset default entities for
the command families to remove the dead pointers to the deleted
proxy objects.

It is possible for a zero-length anti-clogging token payload to cause
IWD to abort. If the length passed into sae_process_anti_clogging was
1, l_memdup would be called with a size of -1. This will cause malloc
to abort.
Fix this by checking for a minimum packet length and dropping the
packet if the length is too small.
The HS20 indication element should always be included during
(Re)Association per the spec. This removes the need for a
dedicated boolean, and now the hs20_ie can be used instead.
The hotspot spec specifically mentions the roaming consortium OI be
3 or 5 bytes long. This requirement also prevents potential buffer
overflows if the user were to configure a long roaming consortium OI.
If the scan was triggered and later aborted, make sure to reset the
triggered value when the CMD_NEW_SCAN_RESULTS event comes in.

Simply prints the ANQP ID (human readable) and the length. Once
the ANQP dependency on netdev is removed the full ANQP parser
can be used, but for now its done manually. Once this is done it
will be much easier to print the actual ANQP ID data.
In the same fashion as the WSC WFA OUI, ie.[ch] will now expose the
other vendor OUIs to avoid duplication across multiple files in IWD
as well as used in iwmon.
P2P probe requests are to be sent at min 6.0 Mb/s using OFDM,
specifically the 802.11b rates are prohibited (section 2.4.1 in Wi-Fi
P2p Technical Spec v1.7), some of which use CCK modulation. This is
already the default for 5G but for 2.4G the drivers generally do this
if we set the NL80211_ATTR_TX_NO_CCK_RATE flags with
NL80211_CMD_TRIGGER_SCAN.
The length check was incorrectly assuming that PPS MO ID or
ANQP Domain ID would be present in the IE. Both these are optional
and without then the minimum length is 5 bytes, not 7.
