2011-09-21iwlagn: remove the callback in host commandsEmmanuel Grumbach1-3/+5
Before this patch, the upper layer could register a callback for each host command. This mechanism allowed the upper layer to have different callbacks for the same command ID. In fact, it wasn't used and the rx_handlers is enough: same callback for all the command with a specific command ID. The iwl_send_add_station needs the access the command that was sent while handling the response (regardless if the command was sent in SYNC or ASYNC mode). So now, all the handlers receive the host command that was sent. This implies a change in the handler signature.

2011-08-29iwlagn: reclaim the packets in transport layerEmmanuel Grumbach1-268/+3
The reclaim flow is really transport related. Define a simple API to allow the upper layer to request from the transport layer to reclaim packets until an index written in the Tx response / BA notification. The transport layer prepares a list of the packets that are being freed and passes this list to the upper layer. Between the two layers, the CB of the skb is used to pass a pointer to the context (BSS / PAN) in which the skb was sent.

2011-08-29iwlagn: bus layer chooses its transport layerEmmanuel Grumbach1-5/+5
Remove iwl_transport_register which was a W/A. The bus layer knows what transport to use. So now, the bus layer gives the upper layer a pointer to the iwl_trans_ops struct that it wants to use. The upper layer then, allocates the desired transport layer using iwl_trans_ops->alloc function. As a result of this, priv->trans, no longer exists, priv holds a pointer to iwl_shared, which holds a pointer to iwl_trans. This required to change all the calls to the transport layer from upper layer. While we were at it, trans_X inlines have been renamed to iwl_trans_X to avoid confusions, which of course required to rename the functions inside the transport layer because of conflicts in names. So the static API functions inside the transport layer implementation have been renamed to iwl_trans_pcie_X. Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is confusing since the registration doesn't mean to request IRQ, so I added a handler for that.

2011-07-11iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic stateMeenakshi Venkataraman1-2/+104
WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
