2011-10-13cw1200: Add 2byte hole in TXreq for unaligned bufAjitpal.Singh
Adds a 2 bytes hole in the WSM Transmit request when skb->data is aligned at 2 bytes.This will make the transmit request 4byte aligned. This optmisation is need for DMA. The firmware is informed about the hole by setting BIT7 in the WSM Transmit Request flags.

2011-10-13cw1200: Accurate reporting of TX status.Dmitry Tarnyagin
* Accurate reporting of TX status is implemented (needed for UAPSD and PSPOLL). * Leaking of TX rate policies is fixed. * skb destructor is implemented. * Time to live for queued frames is implemented. * cw1200_tx is split by separate TX handlers (like in mac80211). * cw1200_skb_to_wsm is not existing anymore. * BT coex: null frames are prioritized as management frames. * Debug: added printing of rate policies in use.

2011-10-13cw1200: AP PS refactoring.Dmitry Tarnyagin
* buffered_multicasts_lock was renamed to ps_state_lock. Previous name was quite confusive. * Per-STA rx_queue was created for early RX-ed frames. Not that we really need these frames, but PM status they are holding is important. * priv->tx_suspend_mask was removed, driver is not using it. It was intended for UAPSD and is not needed in current implementation on mac80211. * Fix: cw1200_queue_unlock() was not called from cw1200_queue_clear() when queue was internally locked.

2011-10-13cw1200: queue dependency refactoring.Dmitry Tarnyagin
According to the driver design queue should know as less as possible about other components. Last commits violate this "rule" by transpatent arguments like tid. This patch is fixing these violations. No functional changes in this commit.

2011-10-13cw1200: PM state in AP mode could be out of sync.Dmitry Tarnyagin
PM state is controlled separately by firmware and driver. Firmware does not update own PM state when STA is removed, so PM state of the driver and firmware could be out of sync. The patch implements resyncronization of the PM state.
