* iwlagn: iwl_rx_queue moves to the iwl_trans_pcieEmmanuel Grumbach2011-08-296-144/+184

* iwlagn: bus layer chooses its transport layerEmmanuel Grumbach2011-08-2924-170/+226
| | | | | | | | | | | | | | | | | | | | | | | 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.

* iwlagn: introduce struct iwl-shared - known by all layersEmmanuel Grumbach2011-08-295-23/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This struct will hold pointers to all the layers, so that every layer will find the pointers it needs when calling another layer. Note that the drv_data set to struct device is now a pointer to struct iwl_shared. This solves of bug that I introduced in iwlagn: simplify the bus architecture Bug description: sysfs gets the the driver data from struct device. Till the aforementioned patch, dev_get_drvdata would return iwl_priv. After the patch, dev_get_drvdata return iwl_bus which is buggy since the sysfs handlers rely on this value, and sysfs handlers need iwl_priv. Now, dev_get_drvdata return iwl-shared. Since we have pointers to all the layers in iwl_shared, every layer will be able to get the pointer it needs: bus layer will gets iwl_bus from the PCI suspend callbacks, and the sysfs handlers will get the iwl_priv they need. In order to keep good encapsulation, we need to avoid to dereference iwl_priv from a different layer. This is why instead of including iwl-dev.h from iwl-shared.h, I added a forward declaration to iwl_priv. Moreover we keep type safety while providing encapsulation.

Allow tx/rx from the device role. In order to tx/rx packets while the stations is not associated (e.g. auth req/resp), the device role has to be used, along with ROC on its link. Keep the logic similiar to the one used in dummy_join. However, since we can't scan while we ROC, we add CROC before starting a scan, and ROC again (if needed) on scan complete. 2. Keeping the antenna for a specific link. We ROC until the connection was completed (after EAPOLs exchange) in order to prevent BT coex operations from taking the antenna and failing the connection (after this stage, psm can be used). During association, we ROC on the station role, and then CROC the device role, thus assuring being ROC during all the connection process. Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap to indicate what roles are currently ROCed. Add wl12xx_roc/croc functions in order to wrap the roc/croc commands while taking care of the roc bitmap. The current ROC/CROC state-machine is a bit complicated. In the future we'll probably want to use wpa_supplicant to control the ROC during connection. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
