2013-12-11zd1211rw: Fix FSF address in file headersJeff Kirsher
Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

2013-12-09ath9k: Update high power gain table for AR9300Sujith Manoharan

2013-12-09ath9k: Use a separate TX gain table for WZR-HP-G450HSujith Manoharan
The Buffalo device WZR-HP-G450H uses the index 3 for TX gain, which is set to the high_power table currently. Later variants of the router use the same index, but instead refer to the low_ob_db gain table. This is not handled in the driver since there is no way to distinguish board revisions and the high_power table is used (incorrectly) for the newer variants. By default, devices based on AR9300 using the TX gain index 3 have to use the high_power table. To make sure that WZR-HP-G450H is not broken when the high_power table is updated, use a separate array based on information obtained from the platform data. The current situation where only the original variant of WZR-HP-G450H works properly stays unchanged. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2013-12-09iwlwifi: mvm: rs: overhaul search cycle state machineEyal Shapira
Rewrite the search cycle state machine to use a more data oriented approach where the different Tx columns (configs) limitations and next columns to search are reprsented in tables which are easy to change. This overhaul also includes several major fixes: 1. Prevent going back to a specific Tx column in a search cycle if it was already explored. 2. Avoid switching to a Tx column that doesn't have any chance if it performs perfectly to beat the current throughput we're getting. These issues were degrading throughput as they were causing switching to "bad" Tx columns. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-12-09iwlwifi: mvm: rs: use the proper channel width define for legacy rateEyal Shapira

2013-12-09iwlwifi: mvm: rs: fix mapping from HT/VHT rates to legacyEyal Shapira
The table rs_ht_to_legacy is used to get the next legacy rate following the last HT or VHT rate in the LQ rates table. The mapping wasn't correct as well as didn't include entries for MCS8/9 which led to out of bounds access. This didn't trigger a crash but led to legacy rate entries using 1Mbps rate. In 5Ghz this probably caused the Tx to fail completely given that Tx attempt would have reached the legacy entries and 1Mbps isn't valid.

2013-12-09iwlwifi: mvm: rs: refactor to use rs_rateEyal Shapira
Introduce rs_rate which represents a rate. Use this structure instead of iwl_scale_tbl_info where we're dealing with a single rate. This avoids allocating the big iwl_scale_tbl_info structure on the stack in several cases like converting to ucode rate format or from ucode rate format.

2013-12-09iwlwifi: mvm: rs: update expected TPT tables if aggregation changedEyal Shapira
Expected TPT table was updated only when switching to a new modulation. This is wrong as toggling aggregation changes the expected TPT signficantly. This leads to scenarios where turning aggregation on after being in MIMO sends us back to SISO despite a perfect success ratio. This occurred because the TPT of the SISO mode was being estimated based on aggregation while the MIMO one wasn't. Also remove an error print which isn't an error anymore since we might be updating the expected TPT table due to aggregation changes.
