2012-02-03iwlwifi: give trans to all the read / write functionsEmmanuel Grumbach1-0/+2
From now on, the transport layer in charge of providing access to the device. So change all the driver to give a pointer to the transport to all the low level functions that actually access the device.

2012-02-03iwlwifi: allocate the transport from the bus layerEmmanuel Grumbach1-6/+15
Change the way we alloc the transport on the way. Since the transport is allocated from a bus specific area, we can give the bus specific parameters (i.e. pci_dev for PCI) to the transport. This will be useful when the bus layer will be killed. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

2011-09-22iwlagn: remove the callback in host commandsEmmanuel Grumbach1-3/+4
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: move the disable agg logic to transport layerEmmanuel Grumbach1-4/+8

2011-08-29iwlagn: move the check_empty logic to the transport layerEmmanuel Grumbach1-5/+6
This logic is responsible to tell mac80211 when the HW queues are empty and the BA session can be started / torn down. Fix a bug on the way: When the the Tx BA session is stopped and the HW queues aren't empty, we stop the SW queue to drain the HW queue and then switch to the legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state. While in this state, we never wake the SW queue, even when the HW queue is almost empty, since we need to drain it completely. Look at iwl_trans_pcie_reclaim regarding this. Once the HW queue is really empty, we must wake the SW queue in order to get traffic to the legacy queue. This step was missing leading to an odd situation were the traffic would just stall after we tore down a Tx BA session while the HW queue was not empty.

the mapping tx_queue -> fifo is really transport related. The upper layer should be involved in such things.

The reclaim flow is really transport related.

2011-08-29iwlagn: bus layer chooses its transport layerEmmanuel Grumbach1-33/+50
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.
