2011-11-11cfg80211: merge in beacon ies of hidden bss.Dmitry Tarnyagin
The problem with PSM when a hidden SSID was used was originally reported by Juuso Oikarinen. - When generally scanning, the AP is getting a bss entry with a zero SSID. - When associating, a probe-req is sent to the AP with the SSID, and as a result a probe-response is received with the hidden SSID in place. As a consequence, a second bss entry is created for the AP, now with the real SSID. - After association, mac80211 executes ieee80211_recalc_ps(), but does not switch to powersave because the beacon-ies are missing. As result, the STA does not ever enter PSM. The patch merges in beacon ies of hidden bss from beacon to the probe response, creating a consistent set of ies in place. Patch is depended on "cfg80211: fix cmp_ies" made by Johannes. Signed-off-by: Dmitry Tarnyagin <dmitry.tarnyagin@stericsson.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-11-09cfg80211/mac80211: allow management TX to not wait for ACKJohannes Berg
For probe responses it can be useful to not wait for ACK to avoid retransmissions if the station that sent the probe is already on the next channel, so allow userspace to request not caring about the ACK with a new nl80211 flag. Since mac80211 needs to be updated for the new function prototype anyway implement it right away -- it's just a few lines of code.

We only need to set the skb queue twice: 1. by the netdev, on local TX. 2. when forwarding a mesh frame. We only need to set the qos header twice: 1. by mac80211, on local TX. 2. when putting a frame on the mpath->frame_queue We also don't need the RA in order to set the proper queue mapping since all mesh STAs are QoS, indicate this and do it once when the frame is received.

2011-11-09mac80211: Avoid filling up mesh preq queue with redundant requestsJavier Cardona
Don't accept redundant PREQs for a given destination.

The 802.11s protocol has a provision to limit the rate of path requests (PREQs) are transmitted (dot11MeshHWMPpreqMinInterval) but there was no limit on the rate at which PREQs were being queued up. There is a valid reason for queuing PREQs: this way we can even out PREQ bursts. But queueing multiple PREQs for the same destination is useless.
