Enable HT aggregation when it reach reasonable traffic without checking traffic load which delay enabling the aggregation and lower the throughput but this behavior can be overwrite by module parameter this address https://bugzilla.kernel.org/show_bug.cgi?id=40042 Signed-off-by:

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. Signed-off-by:

It will hold declaration of functions and forward declaration of struct that are used by several layers. This will allow modules not to include iwl_priv. iwl_bus and iwl_trans are still visible to all. All the layers share the module parameters, move the struct to iwl-shared.h. Also add all module parameters to iwl_mod_params instead of having them as global static. This includes * debug_level * ant_coupling * bt_ch_announce * wanted_ucode_alternative Signed-off-by:

The previous P2P implementation turned out to not work well and new uCode capabilities were added to support P2P. Modify the driver to take advantage of those, and also discover P2P support automatically based on a uCode flag instead of having a Kconfig symbol for P2P. Signed-off-by:

Implement WoWLAN support in iwlagn. The device supports a number of wakeup triggers and can do GTK rekeying when asleep (if HW crypto is used). Unfortunately, we need to disconnect from the AP after resume since we can't yet get all the info out of the wowlan uCode to stay connected safely. Signed-off-by:

It still holds a pointer to iwl_priv. But hopefully this will disappear at some point. Also add the multiple inclusion protection to iwl-trans.h that was forgotten. Move iwl-trans structures to iwl-trans.h Signed-off-by:

Since all the irq / tasklet is now handled in the transport layer, it should give an API to ensure that all the irq / tasklet have finished running. This will allow the upper layer to release all its resources. Signed-off-by:

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:

Now, there are only two functions to send a host command: * send_cmd that receives a iwl_host_cmd * send_cmd_pdu that builds the iwl_host_cmd itself and received flags The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API functions. Kill the unused flags CMD_SIZE_NORMAL / CMD_NO_SKB on the way. Signed-off-by:

Bus specific layer must know how to return the struct device* of the device. Implement that as a callback of iwl_bus_ops and use that callback instead of using the priv->pdev pointer which is meant to disappear soon. Since the struct device * is needed in hot path, iwl_bus holds a pointer to it instead of calling get_dev all the time. Signed-off-by:
