An AP might refuse to connect a STA if it has a low RSSI. In such case,
the AP informs the STA with the desired RSSI delta and a retry timeout.
Any subsequent association attempt with that AP (BSS) should be avoided,
unless the RSSI level improved by the desired delta or the timeout has
expired.
Defined in Wi-Fi Alliance Optimized Connectivity Experience technical
specification v1.0, section 3.14 (RSSI-based association rejection
information).

The purpose of Multi-AP specification is to enable inter-operability
across Wi-Fi access points (APs) from different vendors.
This patch introduces one new configuration parameter 'multi_ap' to
enable Multi-AP functionality and to configure the BSS as a backhaul
and/or fronthaul BSS.
Advertise vendor specific Multi-AP capabilities in (Re)Association
Response frame, if Multi-AP functionality is enabled through the
configuration parameter.
A backhaul AP must support receiving both 3addr and 4addr frames from a
backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
WEP), we can safely call hostapd_set_wds_encryption() as well and we can
reuse the entire WDS condition.
To parse the Multi-AP Extension subelement, we use get_ie(): even though
that function is meant for parsing IEs, it works for subelements.

This extends the SAE implementation in both infrastructure and mesh BSS
cases to allow an optional Password Identifier to be used. This uses the
mechanism added in P802.11REVmd/D1.0. The Password Identifier is
configured in a wpa_supplicant network profile as a new string parameter
sae_password_id. In hostapd configuration, the existing sae_password
parameter has been extended to allow the password identifier (and also a
peer MAC address) to be set. In addition, multiple sae_password entries
can now be provided to hostapd to allow multiple per-peer and
per-identifier passwords to be set.

Mark a channel as required DFS based on regulatory information received
from the driver/kernel rather than deciding based on hardcoded
boundaries on the frequency. Previously few channels were being marked
as requiring DFS even though they were non-DFS in a particular country.
If the driver does not provide channel list information, fall back to
the previously used frequency-based determination.
