This patch series adds initial support for Multi-Link operation AP. First, it refactors the driver_nl80211 to support multiple links by introducing internal structs to hold the links and API's to configure links and link stations. Next it allows to start multiple hostapd_iface's and bind them to the same underlying network interface and driver instance. Each hostapd_iface represents a separate link BSS. The events are forwarded to the correct hapd according to the link id. Afterwards we implement advertising and parsing of basic MLE and RNR in beacons, probe responses and during authentication and association stages. Finally, implement WPA authenticator for MLO and also adjust SAE to use the MLD addresses for commit derivation. It needs to be noticed, that this series are minimal and add a very basic MLO implementation which allow to establish SAE/OWE connection and intended to be used mainly for testing purposes.
