2010-06-26iwlwifi: add disable rf calibration support for 6000g2a and 6000g2bWey-Yi Guy1-0/+16
Radio calibration (chain noise and sensitivity) should be allowed to be disabled from debugfs if compiled with CONFIG_IWLWIFI_DEBUGFS. For both 6000g2a and 6000g2b, the parameters are missing in "cfg", which cause user can not disable the radio calibration manually; add the support to allow the operation.

2010-06-26iwlwifi: update LQ for bcast station on channel changeDaniel Halperin1-0/+1
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.

2010-05-11iwlwifi: rework broadcast station managementJohannes Berg1-2/+0
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.

2010-05-11iwlwifi: remove ucode virtual functionsJohannes Berg1-2/+0
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.

2010-05-11iwlwifi: manage IBSS station properlyJohannes Berg1-0/+2
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.

2010-01-26iwlwifi: make broadcast station addition genericReinette Chatre1-0/+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.

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.
