* iwlwifi: implement new mac80211 station add/remove callsReinette Chatre2010-03-191-4/+7
| | | | | | | | | | | | | | mac80211 recently implemented two new callbacks that are used to request station add/remove from the driver. The benefot from these new callbacks are that they enable the driver to sleep while performing this work. This is a big patch since a few things need to be coordinated in this move. First we need to decouple station management from rate scaling, which caused a lot of code to be moved and/or deleted. Next we needed to tie in with mac80211's station management callback and let it direct our station management as well as trigger the rate scaling initialization.

* iwlwifi: only add broadcast station onceReinette Chatre2010-03-191-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the broadcast station is added after every RXON command. Change this to only add the broadcast station when interface is added by mac80211. With this we need some extra work to ensure broadcast station is always present since station table is cleared when RXON without ASSOC bit set is sent. To deal with this we re-add all driver known stations to uCode after such an RXON command is sent. We also do some cleanup and remove the various calls to clear the station table. We now only clear the station table in two scenarios: - only clear uCode portion of station table when RXON command without ASSOC bit is sent - clear uCode and driver portion when interface goes down or is removed. We need to do this clearing when interface goes down to deal with the device restart/reconfigure routines which do not remove the interface, but do add the interface during reconfiguration. Previously the keys were also cleared when station table in driver is cleared, this is not done anymore since mac80211 will take care that keys are set and cleared correctly. There is a known issue with this change. Associating with different AP without bringing interface down fails with a firmware error. This is because of the lack of full station notification support and the later patches in this series that complete the station notification support will fix this.

* iwlwifi: make broadcast station addition genericReinette Chatre2010-01-251-0/+1
| | | | | | | | | | | | | | | | | | Add function pointer for broadcast station addition so that we can call it in from iwlcore at a later time. We only distinguish between iwlagn and iwl3945 broadcast station addition. For the iwl3945 station addition we add that function to iwlcore since that is where most station functionality resides, making it part of iwl3945 will require significant code reorganization that will dilute station management functionality. This seems to be an efficient solution. It may seem as though we are removing error checking when adding the 3945 broadcast station but this error checking was never really necessary since the function returns the station id and the broadcast station id is always set.

* iwlwifi: handle unicast PS bufferingJohannes Berg2009-11-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the new mac80211 functionality, this makes iwlwifi handle unicast PS buffering correctly. The device works like this: * when a station goes to sleep, the microcode notices this and marks the station as asleep * when the station is marked asleep, the microcode refuses to transmit to the station and rejects all frames queued to it with the failure status code TX_STATUS_FAIL_DEST_PS (a previous patch handled this correctly) * when we need to send frames to the station _although_ it is asleep, we need to tell the ucode how many, and this is asynchronous with sending so we cannot just send the frames, we need to wait for all other frames to be flushed, and then update the counter before sending out the poll response frames. This is handled partially in the driver and partially in mac80211. In order to do all this correctly, we need to * keep track of how many frames are pending for each associated client station (avoid doing it for other stations to avoid the atomic ops) * tell mac80211 that we driver-block the PS status while there are still frames pending on the queues, and once they are all rejected (due to the dest sta being in PS) unblock mac80211 Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* iwlwifi: split adding broadcast station from othersReinette Chatre2009-11-021-0/+1
| | | | | | | | | | In preparation for some station management changes we split the addition of a broadcast station from the other stations. Later we will rely on mac80211 to direct all management (addition/removal) of all stations except the broadcast station.
