2011-09-14iwlagn: iwl-trans.c can't dereference iwl_priv any moreEmmanuel Grumbach1-0/+15
This reaches encapsulation for this file. In order to reach this: * move priv->valid_context to iwl_shared * move the last_rejected initialization to the upper layer * define a wrapper iwl_nic_config in the upper layer that calls to cfg->lib->ops->nic_config Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-09-14iwlagn: clean up of transport layerEmmanuel Grumbach1-0/+92
Move a few declarations needed by the transport layer to iwl-shared.h Move iwl_cmd_meta, iwl_tx_queue and friends to the internal transport header file. Move iwl_device_cmd iwl_host_cmd and friends to iwl-trans.h since these structs are used in the API to the transport layer. Move get_cmd_string to the upper layer with a declaration in iwl-shared.h.

2011-09-14iwlagn: remove priv dereferences from the transport layerEmmanuel Grumbach1-1/+2
Another round of clean up on the transport layer. Define a wrapper around wiphy_rfkill_set_hw_state to prevent the transport layer from accessing priv->hw. Also move wait_command_queue to the transport layer. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-08-29iwlagn: move the stop / wake queue logic to transport layerEmmanuel Grumbach1-0/+61
priv->mac80211_registered and priv->hw needed to move to shared. stop_queue API was added in order to allow the upper layer to stop the SW queues for regulatory purposes.

2011-08-29iwlagn: move the disable agg logic to transport layerEmmanuel Grumbach1-1/+4
Since all the check_empty logic is now in the transport layer, the upper layer doesn't need to know anything about tx queues. The disable aggregation flow was the last to know what a tx queue is, so move it too.

2011-08-29iwlagn: move the check_empty logic to the transport layerEmmanuel Grumbach1-2/+2
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.

2011-08-29iwlagn: move the mapping ac to queue / fifo to transportEmmanuel Grumbach1-0/+14
This mapping is transport related. This allows us to remove the notion of tx queue from the tx path in the upper layer. iwl_wake_any_queue moved to transport layer since it needs to access these mappings. The TX API is nicer now: int (*tx)(struct iwl_trans *trans, struct sk_buff *skb, struct iwl_device_cmd *dev_cmd, u8 ctx, u8 sta_id); Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-08-29iwlagn: set tx_fifo for ampdu in transport layerEmmanuel Grumbach1-4/+4
the mapping tx_queue -> fifo is really transport related. The upper layer should be involved in such things. Note that upon agg_disable, the queue is always mapped to fifo 0, but this doesn't matter since when the queue will be setup again for a new BA session, it will be configured to the good fifo anyway.

There are still quite a few, but much less.

2011-08-29iwlagn: bus layer chooses its transport layerEmmanuel Grumbach1-5/+11
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.
