* iwlagn: send simple LQ command for WoWLANJohannes Berg2011-10-141-2/+5
| | | | | | | | | | | | For some reason, WoWLAN doesn't always seem to be happy with more advanced LQ commands. Since we don't need them as we're not going to send a lot of data, simply program the station with the very simple default LQ command.

* iwlagn: remove the callback in host commandsEmmanuel Grumbach2011-09-211-16/+13
| | | | | | | | | | | | | | | | | 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.

* iwlagn: bus layer chooses its transport layerEmmanuel Grumbach2011-08-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | 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: rewrite HW cryptoJohannes Berg2011-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As I just discovered while doing WoWLAN, HW crypto is done wrong for GTKs: they should be programmed for the AP station ID (in the managed mode case) and the HW can actually deal with multiple group keys per station as well (which is useful in IBSS RSN but that I've chosen not to use this). To fix all this, modify the way keys are sent to the device and key offsets are allocated. After these changes, key offsets are stored into the hw_key_idx which we can then track for the key lifetime, not relying on our sta_cmd array. WEP default keys get special treatment, of course. Additionally, since I had the API for it, we can now pre-fill TKIP phase 1 keys for RX now that we can obtain the P1K from mac80211, a capability I had added for WoWLAN initially. Finally, some keys simply don't need to be added into the device's key cache -- a key that won't be used for RX is only needed in the TX header, so "pretend" to have accepted any key without adding it into the device -- no need to use up key space there for it.

| | | | | | | | | | | | | | The rate table in the bcast LQ is computed only when the station is allocated, and chooses the lowest rate for the band. Because of when this occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz beaconing mode, this rate will prevent beacons from being sent and any other packets from being received. We can fix this by re-initializing the bcast station's LQ command when the channel is changed.
