2010-03-10iwmc3200wifi: refuse to associate on unallowed channelsZhu Yi
We need to make sure we don't associate with APs on unallowed channels (according to regulatory setting). This could happen when the channel is not specified (auto-select) within the connection request. In this case we get the AP's channel until the firmware indicates the association succeeded later. We need to verify the associated channel. If the channel is disabled by regulatory, we have to disassociate with the AP. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2009-12-04iwmc3200wifi: Enable wimax core through module parameterSamuel Ortiz

2009-12-04iwmc3200wifi: Add wifi-wimax coexistence mode as a module parameterSamuel Ortiz
Wifi and wimax coexistence mode is set by wifi at boot time. There can be several modes, defined by priority tables.

2009-11-28iwmc3200wifi: 802.11n Tx aggregation supportSamuel Ortiz
To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC. Before sending an AddBA, the UMAC synchronizes with the host in order to know what is the last Tx frame it's supposed to receive before it will be able to start the actual aggregation session. We thus have to keep track of the last sequence number that is scheduled for transmission on a particular RAxTID, send an answer to the UMAC with this sequence number. The UMAC then does the BA negociation and once it's done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification to let us know that we can resume the Tx flow on the specified RAxTID.
