P2P: Skip GO Neg Conf ack failure workaround of send failures The workaround to ignore no ctrl::ack received for GO Negotiation Confirmation frame was only supposed to be used when the frame was actually transmitted and just the ack was not received. However, due to the way the driver failure on transmitting the frame were reported, this ended up getting applied for all failures in sending the GO Negotiation Confirmation frame. Improve this by providing a mechanism to indicate whether send_action operations fail locally before the frame was actually transmitted or because of not receiving ack frame after having transmitted the frame.

P2P: Add automatic GO Negotiation vs. join-a-group selection p2p_connect command can now be used with an optional "auto" parameter to request wpa_supplicant to determine automatically whether to use join-a-group operation (if the peer is operating as a GO) or group formation. This makes it easier for external programs to handle connection type selection by offloading this to wpa_supplicant. The previously used p2p_connect join commands can be replaced with p2p_connect auto to use this new mechanism. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

This can be used as an alternative to inviting a new P2P peer to join the group (i.e., use GO Negotiation with GO intent 15 instead of starting an autonomous GO and using invitation), e.g., in case a GO Negotiation Request is received from a peer while we are not running as a GO. The persistent group to use for parameters is indicated with persistent=<network id> parameter to p2p_connect. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

Pass signal strength through, fix units The signal strength is currently never used as the only driver reporting it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never populated by the kernel. The kernel will (soon) populate IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that. Also, since it was never really populated, we can redefine the signal field to be in dBm units only. My next patch will also require knowing the signal strength of probe requests throughout the code (where available), so add it to the necessary APIs.

P2P: Do not request station mode scans during P2P operations The P2P search mechanism depends on the same scan functionality that is used for station mode scans. If these operations are being used at the same time, scan result processing is not handled properly. Avoid unexpected behavior by delaying station mode scan requests if a P2P operation is in progress. Among other things, this allows the station mode connection attempt to be continued after a P2P find or group formation has been completed if the interface is available (i.e., when the P2P group uses a separate virtual interface).

P2P: Allow older scan results to improve p2p_connect-auto robustness Previusly the peer was assumed to not be operating a GO if the BSS entry for it was not updated in the single scan run started by p2p_connect-auto. This is not very robust since a scan may miss the peer if either a Probe Request or Probe Response frame is lost. Improve robustness by assuming the peer is still operating the GO and starting the join operation. If the GO is not found during PD-for-join or the single-channel scans during the join, fall back to GO Negotiation. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
