2010-10-07iwlwifi: remove apm_ops.stopJohannes Berg
Since all devices share the same operation here, there's no need to call it indirectly. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-10-07iwlwifi: remove set_pwr_src operationJohannes Berg
The set_pwr_src operation is only ever used from within the same sub-driver that it is declared in, so it can just be called directly instead of being an operation. Also, it is never called to set the power source to V_aux, so change the two functions accordingly (but keep the V_aux code for documentation purposes in a comment).

2010-10-07iwlwifi: remove set_ct_kill operationJohannes Berg
This operation is only ever called from set_hw_params, which is also already based on the config/ops, so that there's no need to have a separate set_ct_kill op and we can just call the right ct_threshold function.

2010-10-06iwlagn: reduce redundant parameter definitionsWey-Yi Guy
move paramater definitions to a device paramater structure only leaving the device name, which antennas are used and what firmware file to use in the iwl_cfg structure. this will not completely remove the redundancies but greatly reduce them for devices that only vary by name or antennas. the parameters that are more likely to change within a given device family are left in iwl_cfg. also separate bt param structure added to help reduce more.

2010-08-09iwlagn: fix rts cts protectionJohannes Berg
Currently the driver will try to protect all frames, which leads to a lot of odd things like sending an RTS with a zeroed RA before multicast frames, which is clearly bogus. In order to fix all of this, we need to take a step back and see what we need to achieve: * we need RTS/CTS protection if requested by the AP for the BSS, mac80211 tells us this * in that case, CTS-to-self should only be enabled when mac80211 tells us * additionally, as a hardware workaround, on some devices we have to protect aggregated frames with RTS To achieve the first two items, set up the RXON accordingly and set the protection required flag in the transmit command when mac80211 requests protection for the frame. To achieve the last item, set the rate-control RTS-requested flag for all stations that we have aggregation sessions with, and set the protection required flag when sending aggregated frames (on those devices where this is required). Since otherwise bugs can occur, do not allow the user to override the RTS-for-aggregation setting from sysfs any more. Finally, also clean up the way all these flags get set in the driver and move everything into the device-specific functions.

2010-07-02iwlwifi: add support for device tx flush requestWey-Yi Guy
"Flush" request can come from two different sources, it can either from mac80211, or from device when the operation is needed. Here adding the support for device issue "flush" request. When receive tx complete with status is TX_STATUS_FAIL_RFKILL_FLUSH, issue REPLY_TXFIFO_FLUSH command to uCode to flush out all the tx frames in queues. In this condition, since mac80211 has no knowledge of "flush" operation, driver need to stop all the tx queues and wait for the operation completed before wake up the queues for frames transmission.

Adding flush callback support in the driver. Two type of flush can be issued by mac80211: 1. drop = true: frame drop is ok, issue REPLY_TXFIFO_FLUSH host command to uCode to drop all the frames in tx fifo queues; then return the control back to mac80211 2. drop = false: wait for either all the frames in tx fifo queues been transmitted, or timeout; then return the control back to mac80211 If the flush request coming from mac80211, mac80211 will make sure there are no additional frames push down to driver before flush operation is completed.

2010-06-25iwlwifi: update LQ for bcast station on channel changeDaniel Halperin
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.

When driver pass the beacon related timing information to uCode in both spectrum measurement and channel switch commands, the beacon timing parameter require in uCode beacon format; those helper functions will do the conversation from uSec to the correct uCode format Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-05-10iwlwifi: rework broadcast station managementJohannes Berg
Currently, the broadcast station is managed along with the interface type, rather than always being present. That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.

2010-05-10iwlwifi: remove ucode virtual functionsJohannes Berg
AGN devices all use the same ucode operations, except for 4965, because 4965 uses only v1 file headers. Therefore, we can remove all the indirection we have here and just code the API distinction in place, with a small special case for 4965.

2010-05-10iwlwifi: manage IBSS station properlyJohannes Berg
Currently iwlwifi will eventually exhaust the station table when adding the BSSID station for IBSS mode, unless the interface is set down. The new mac80211 ibss joined/left notification allows us to fix that easily by moving the code to add the IBSS station to the notification, and also adding code to remove it again when we leave the IBSS.

2010-01-25iwlwifi: make broadcast station addition genericReinette Chatre
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.

2010-01-25iwlwifi: Tune radio to prevent unexpected behaviorTrieu 'Andrew' Nguyen
We have seen the throughput dropped due to external noisy environment and the radio is out of tune. There are lot of plcp errors indicating this condition. Eventually the station can get de-authenticated by the Access Point. By resetting and tuning the radio, the plcp errors are reduced or eliminated and the throughput starts to rise. To prevent unexpected behavior such as drop in throughput or deauthentication, - The change provides the driver feature to monitor and tune the radio base on the statistics notification from the uCode. - It also allows the setting of the plcp error rate threshold via the plcp_delta under debugfs interface.
