* mac80211: do not enable ps if 802.1x controlled port is unblockedJason Young2011-03-111-0/+4
| | | | | | | | | | | | | | | | If dynamic_ps is disabled, enabling power save before the 4-way handshake completes may delay the station from being authorized to send/receive traffic, i.e. increase roaming times. It also may result in a failed 4-way handshake depending on the AP's timing requirements and beacon interval, and the station's listen interval. To fix this, prevent power save from being enabled while the station isn't authorized and recalculate power save whenever the station's authorized state changes.

* mac80211: support direct offchannel TX offloadJohannes Berg2011-02-251-0/+39
| | | | | | | | | | | | | For devices supported by iwlwifi sometimes off-channel transmissions need to be handled by the device completely. To support this mac80211 needs to pass the frame directly to the driver and not through the TX path as the driver needs the frame and channel information at the same time.

| * mac80211: fix TX status cookie in HW offload caseJohannes Berg2011-02-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the off-channel TX is done with remain-on-channel offloaded to hardware, the reported cookie is wrong as in that case we shouldn't use the SKB as the cookie but need to instead use the corresponding r-o-c cookie (XOR'ed with 2 to prevent API mismatches). Fix this by keeping track of the hw_roc_skb pointer just for the status processing and use the correct cookie to report in this case. We can't use the hw_roc_skb pointer itself because it is NULL'ed when the frame is transmitted to prevent it being used twice. This fixes a bug where the P2P state machine in the supplicant gets stuck because it never gets a correct result for its transmitted frame.

| | | | | | | | | | | | | | | | | | | | Some were indirectly set to NO_HT (zero), but I think it's better to explicitly set it in case the enum ever changes.

* cfg80211/mac80211: add mesh join/leave commandsJohannes Berg2010-12-061-9/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of tying mesh activity to interface up, add join and leave commands for mesh. Since we must be backward compatible, let cfg80211 handle joining a mesh if a mesh ID was pre-configured when the device goes up. Note that this therefore must modify mac80211 as well since mac80211 needs to lose the logic to start the mesh on interface up. We now allow querying mesh parameters before the mesh is connected, which simply returns defaults. Setting them (internally renamed to "update") is only allowed while connected. Specify them with the new mesh join command instead where needed. In mac80211, beaconing must now also follow the mesh enabled/not enabled state, which is done by testing the mesh ID.

| | | | | | | | | | | | | | | | With p2p, it is sometimes necessary to transmit a frame (typically an action frame) on another channel than the current channel. Enable this through the CMD_FRAME API, and allow it to wait for a response. A new command allows that wait to be aborted. However, allow userspace to specify whether or not it wants to allow off-channel TX, it may actually want to use the same channel only.
