2012-03-12iwlwifi: Add bool mvm_ucode to iwl_fwDavid Spinadel2-1/+10
mvm_ucode is true when mvm TLVs arive. Signed-off-by: David Spinadel <[email protected]> Signed-off-by: Wey-Yi Guy <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2012-03-12iwlwifi: change struct iwl_fwDavid Spinadel7-141/+139
Change iwl_fw struct to hold an array of fw_img instead of three separated instances. Change fw_img to hold an array of fw_desc instead of two separate descriptors for instructions and data. Change load_given_ucode, load_section, verification functions etc. to support this structure.

2012-03-12iwlwifi: Add TLVs and fields for 16.0 uCodeDavid Spinadel4-16/+108
New TLVs for ucode sections that are not known as instruction or data. New TLVs for phy-configuration and default calibrations. Add default calib and phy config fields to iwl_fw.

2012-03-12iwlwifi: more modularity in fw images and sectionsDavid Spinadel3-77/+207
Changed iwl_firmware_pieces structure to support an array of separate images, and an array of sections for each image. In fw_sec and fw_desc structures, added a field for offset from the HW address, to support 16.0 uCode that provides an offset instead of any other data about the section. This field is filled with default values when parsing instruction or data section.

2012-03-12iwlwifi: explicitly track whether INIT uCode was runDavid Spinadel3-5/+6
Remove IWL_UCODE_NONE from enum iwl_ucode_type which, by being the default value in 0-initialized memory, implicitly allowed us to track whether any uCode had ever been loaded successfully (which would have been the INIT uCode) and instead explicitly track whether or not INIT uCode has been run.

2012-03-12iwlwifi: move wait_command_queue from shared to transMeenakshi Venkataraman8-10/+11
This wait queue really belongs to the transport layer, as it is used for sending synchronous commands to the HW. However, only op_mode knows about errors and exceptional conditions, so make this queue accessible by the op_mode.

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround warning with a statistics notification, this means we can't just remove it as we'd hoped. Abstract it out so that the higher layer can configure this as a kind of "filter" in the transport.

2012-03-12rt2x00: Fix beacon skew in rt2800pciHelmut Schaa2-0/+33
rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by: Helmut Schaa <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2012-03-12mac80211: Disable MCS > 7 in minstrel_ht when STA uses static SMPSHelmut Schaa1-0/+9
Disable multi stream rates (MCS > 7) when a STA is in static SMPS mode since it has only one active rx chain. Hence, it doesn't even make sense to sample multi stream rates. Signed-off-by: Helmut Schaa <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2012-03-12mac80211: set channel back after disassociatingJohannes Berg1-7/+6
As we've discussed, we want to avoid channel changes while associated. While the part when we actually associate needs a bit more work, the bit that happens on disassociating can be changed quite easily. Move the channel type change later in the disassociate process to set the channel only after the driver was told that it's now disassociated. As the driver could expect powersave to be enabled only when associated, this thus results in splitting the config call, but overall what happens makes more sense this way.

2012-03-12mac80211: Limit TID buffering during BA session setup/teardownHelmut Schaa1-0/+6
While setting up or tearing down a BA session mac80211 is buffering pending frames for the according TID. However, there's currently no limit on how many frames are buffered possibly leading to an out-of- memory situation. This can happen on systems with little memory when the CPU is fully loaded since the BA session work is executed in process context while frames can still come via softirq. Apply a limitation to the TIDs pending queue to avoid consuming too much memory in this situation. Signed-off-by: Helmut Schaa <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2012-03-09iwlwifi: restore PAN supportEmmanuel Grumbach2-30/+32
in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice. Document that we are allowed to configure the transport several times before start_fw, but not after.

2012-03-08iwlwifi: don't delete AP station directlyJohannes Berg3-6/+53
With the mac80211 deauth sequence changes, the station is deleted before the device is set unassociated. This can cause the device to get confused as it expects the station to be there while the associated bit is set. To fix this, do not delete the AP station from the device when mac80211 asks for deletion, instead just mark it as unused and rely on the unassociated RXON to drop it from the station database in the device.
