2014-05-06iwlwifi: mvm: rs: choose correct expected tpt tableEyal Shapira1-1/+1
The expected throughput table used when estimating a new column depends on the channel bandwidth. When switching from legacy to siso or mimo the wrong expected throughput table was used as it was chosen based on the the channel bandwidth in legacy which is always 20Mhz. Instead it should be chosen based on the current sta bandwidth which could be also 40Mhz or 80Mhz. When enabling MCS9 this bug leads to a problem where the max expected throughput of the siso or mimo column is 0 as MCS9 isn't supported in 20Mhz. This in turns prevents switching to siso or mimo. Fix this by using the sta bandwidth when deciding which table to choose. Signed-off-by: Eyal Shapira <eyalx.shapira@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-05-06iwlwifi: mvm: rs: avoid TPC while in search cycleEyal Shapira1-1/+2
TPC is a power optimization which should only be attempted when we're in the "stay in column" state after we've locked onto an optimal rate.

2014-05-06iwlwifi: mvm: rs: don't allow TPC when power save is disabledEyal Shapira1-4/+9
Currently we were checking only if the driver power_scheme is set to CAM. TPC shouldn't be enabled also when disabling powersave on the interface (e.g. iw wlan0 set power_save off) which may occur even if power_scheme wasn't set to CAM.

2014-05-06iwlwifi: mvm: rs: overhaul rs_get_best_rateEyal Shapira1-86/+31
rs_get_best_rate determines the optimal rate to try in a new Tx column. Currently we were sometimes trying a too high rate which would lead us to fail and avoid switching to the new column despite it having a potential to be better. Change the logic to try and find the first rate which would exceed the current actual throughput or be more aggressive if the success ratio is good.

2014-05-06iwlwifi: mvm: rs: revert changes to search cycle rulesEyal Shapira1-14/+14
Adding more options in the search cycle causes longer search cycles with additional wondering off to non optimal Tx configurations.

2014-04-30wlcore: fix usage of platform_device_add_data()Christian Engelmayer2-31/+20
Coverity CID 986698 reports leakage of struct wlcore_platdev_data in the probe functions of both the SPI/SDIO interfaces. The structure passed to platform_device_add_data() is dynamically allocated and only freed in the error paths, however, platform_device_add_data() adds a copy of the platform specific data to the device. Move the temporary struct that is kmemdup'ed to the stack. This issue exists since afb43e6d (wlcore: remove if_ops from platform_data).
