2011-05-19ath9k: fix ad-hoc nexttbtt calculationFelix Fietkau
rounding up the delta between last-beacon-tsf and tsf to intval is wrong and can lead to misconfigured timers which breaks beacon transmission. Fix this by adding intval and subtracting the offset of the tsf within the current slot. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-05-19ath9k_htc: Fix max subframe handlingSujith Manoharan
Commit "ath9k_htc: Fix AMPDU subframe handling" registered the maximum subframe limit of the driver with mac80211, which was used in ADDBA negotiation. While technically correct, this causes inter-operability issues with a few APs. Revert to the older behavior to fix this.

2011-05-19ath9k_htc: Fix BSSID calculationSujith Manoharan
The BSSID/AID has to be set for the first associated station interface.

2011-05-19mwifiex: reduce CPU usage by tracking highest_queued_prioMarc Yang
This patch adds highest_queued_prio to track priority of packets as they are enqueued so that mwifiex_wmm_get_highest_priolist_ptr() starts checking at the first level where we have packets, instead of the highest.

2011-05-19ath9k: fix ad-hoc mode beacon selectionFelix Fietkau
In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

2011-05-19cfg80211: Use consistent BSS matching between scan and smeJouni Malinen
cfg80211 scan code adds separate BSS entries if the same BSS shows up on multiple channels. However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

2011-05-13iwlagn: support multiple TBs per commandJohannes Berg
The current "huge" command handling is a bit confusing, and very limited since only one command may be huge at a time. Additionally, we often copy data around quite pointlessly since we could instead map the existing scan buffer for example and use it directly. This patch makes that possible. The first change is that multiple buffers may be given to each command (this change was prepared earlier so callsites don't need to change). Each of those can be mapped attached to a TB in the TFD, and the command header can use a TB (the first one) in the TFD as well. Doing this allows getting rid of huge commands in favour of mapping existing buffers. The beacon transmission is also optimised to not copy the SKB at all but use multiple TBs.
