iwlmei allows to integrate with the CSME firmware. There are flows that are prioprietary for this purpose: * Get the information the AP, the CSME firmware is connected to. This is useful when we need to speed up the connection process in case the CSME firmware has an TCP connection that must be kept alive across the ownership transition. * Forbid roaming, which will happen when the CSME firmware wants to tell the user space not disrupt the connection. * Request ownership, upon driver boot when the CSME firmware owns the device.Vendor command requirements are documented here: https://wireless.wiki.kernel.org/en/developers/documentation/nl80211#vendor-specific_api The commit log is not really answering to those. For example, how a user would use this? Or is there a user space tool?We intend to send those command from the NetworkManager.
I'm not really fond of the idea that NetworkManager uses nl80211 vendor commands, sounds quite hacky to me. I would prefer that NetworkManager uses generic nl80211 interface so that it works with every driver. But I need to look at v4 to understand more how this all works. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
