2009-03-27mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifiJohannes Berg
This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.

By adding an additional hw_params (tfd_size) and a new iwl_lib ops (txq_init), we can now use the iwlcore TX queue management routines. We had to add a new hw_params because we need to allocate the right DMA buffer for TFDs, and those have a different sizes depending if you're on 3945 or agn.

2008-12-05iwlwifi: rely on API version read from firmwareReinette Chatre
This adds the infrastructure to support older firmware APIs. The API version number is stored as part of the filename, we first try to load the most recent firmware and progressively try lower versions. The API version is also read from the firmware self and stored as part of the iwl_priv structure. Only firmware that is supported by driver will be loaded. The version number read from firmware is compared to supported versions in the driver not the API version used as part of filename. An example using this new infrastrucure: if (IWL_UCODE_API(priv->ucode_ver) >= 2) { Driver interacts with Firmware API version >= 2. } else { Driver interacts with Firmware API version 1. } Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
