2011-11-02carl9170: fix AMPDU TX_CTL_REQ_TX_STATUS handlingChristian Lamparter
Previously the driver did not care if TX_CTL_REQ_TX_STATUS was set on aggregated frames or not and it would silently drop successfully sent frames if possible [much like: "no news is good news!"]. But, TX_CTL_REQ_TX_STATUS was invented for a reason and no tx status report should ever be dropped if it is set.

Harshal Chhaya discovered during network tests, that several of his clients dropped-off the network. The captured packets shows that the beacons sent by the AP are at a much lower power than the other data packets. The reason for this mishap: The driver never updated the beacon phy register, so all beacons were always sent at the lowest power.

2011-05-05carl9170: fix allmulticast modeNicolas Cavallari
Currently, the driver only disable multicast filtering when the FIF_ALLMULTI driver flag has been just set (ie, if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else it will reenable multicast filtering. But next time, this condition will be false and multicast filtering will be reenabled, even through FIF_ALLMULTI is still set. This mean that allmulticast only works for less than two minutes in ad-hoc mode. This patch fixes that to disable multicast filtering as long as FIF_ALLMULTI is set.

Some clients seem to rely upon the reception of BlockAckReqs to flush their rx reorder buffer.

2011-02-25mac80211: make tx() operation return voidJohannes Berg
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

2011-01-19mac80211: track receiver's aggregation reorder buffer sizeJohannes Berg
The aggregation code currently doesn't implement the buffer size negotiation. It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable!
