2014-05-15iwlwifi: fix LED support Kconfig dependenciesJohannes Berg
If DVM or MVM are built-in but LEDS_CLASS isn't then the current Kconfig will enable LED support and fail the build. Fix this by making the LED support depend on LEDS_CLASS being built-in or, if it is modular, only enabling it if iwlwifi also is.

2014-05-15iwlwifi: mvm: add uapsd_disable module parameterMatt Chen
Some APs (e.g. TP-LINK TL-WA801N) are disabling aggregation (downlink to station) when U-APSD is enabled, resulting in low throughput. Add a module parameter to allow disabling U-APSD support in the driver. Also re-enable U-APSD for -9 firmware since the firmare issues were fixed in this release. There are devices that won't support U-APSD even with newer firmware, so bring the TLV flag back to detect those.

Fix a bug in nvm_read_section function if size of the section is a multiple of 2K: - if the size of the section is *not* multiple of 2K, then we will have: read(2K) - return 2K ... read(2K) - return 2K read(2K) - return the rest (in bytes) and exit the while loop. - else, if the size of the section is a multiple of 2K, then we have: read(2K) - return 2K read(2K) - return 2K read(2K) - return 2K read(2K) - return 0 and exit the while with an error. We should not return an error in the latter case, because it might well be that the section was completely read. Also, we try now to read all the sections as this is needed for new devices.

2014-05-13iwlwifi: use dev_printk instead of dev_dbg for debug logsLiad Kaufman
When calling IWL_DEBUG_*() dev_dbg() is currently used, and this could result in the log being ignored no matter the internal loglevel, since dev_dbg() may get turned on or off based on the dynamic debug mechanism. Replace the dev_dbg() with dev_printk() since dynamic printing is pointless as we use our own debug level mechanism and there is just a single dev_dbg() call in the code.

2014-05-11iwlwifi: mvm: Disable uAPSD for a DCM clientAvri Altman
A binding object associates virtual MACs to a Phy. Binding object can ask (and get) air time, thus allowing several MACs to share the medium. A binding object can be in either one of 3 states: 1) standalone - A single active MAC 2) Different Channel Mode (DCM) - There are 2 active MACs or more (not necessarily just clients), but each has its own channel. 3) Same Channel Mode (SCM) - There are 2 active MACs or more (not necessarily just clients), that share the same channel. This patch introduces an additional condition for enabling uAPSD: uAPSD should be disabled for a client in DCM. The reason for that is a low latency issue in Miracast.

Read first the nvm sections from the OTP, then read the nvm sections from the external file and override the OTP values (if there were any values in the OTP).

A few devices aren't allowed to be powered up at driver load time. Add "power_up_nic_in_init" flag to iwl_cfg structure to customize the load flow according to the device.

2014-05-06iwlwifi: mvm: rs: choose correct expected tpt tableEyal Shapira
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>

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 Shapira
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.
