In case the AP is an AP MLD, parse the Multi-Link element from the
Authentication frame, store the relevant information, and prepare the

If the AP is not an AP MLD or the parsing of the element fails, continue
the authentication flow without MLD support.
For SAE, it is needed to skip various fixed fields in
the Authentication frame. Implement it for SAE with H2E.
TODO: This should be extended to other authentication algorithms which

Add support for including multiple hostapd interfaces in the same AP
MLD, i.e., all using the same underlying driver network interface.
To do so, when a new hostapd interface is added, if there is already
another interface using the same underlying network interface, associate
the new interface with the same private data object, instead of creating
a new one.
As some of the BSSs are non-first BSSs, meaning that they reuse the
drv_priv of the initial BSS, make sure not to double free it.
Currently multiple BSS entries are not supported so always use bss[0]
for MLD.

AP cannot come up in channels that are marked as NO_IR. If AP moves to
HAPD_IFACE_DISABLED state, it will deinitialize the nl80211 driver
interface and sockets.
Hence, introduce a new state called HAPD_IFACE_NO_IR, for 6 GHz APs to
handle NO_IR scenarios, such as AFC, where the channels not allowed by
AFC will have HOSTAPD_CHAN_NO_IR flag set. In this state, AP is still
kept in a non-operational state (stopped) without deinitializing the
nl80211 driver interface. wiphy reg change event can then update the
channels and bring up the AP in a valid channel.
