2015-10-25iwlwifi: nvm: free old section data when reading nvm fileMoshe Harel1-0/+1
When reading external NVM file, if a section exists both in OTP and in the external file, the memory that was allocated at OTP reading is not freed. This is possible only on systems that have an external NVM file which is typically the case on embedded systems.

This is a workaround to an OTP bug. In Series 8000 1x1, the OTP 0xA052 defines 2x2 antenna configuration. This workaround overrides the decision based on HW id and MIMO disabled bit which is correct in the OTP and set to disabled.

2015-08-04iwlwifi: remove command header flags fieldJohannes Berg1-12/+0
The 'flags' field really has been reserved in the firmware API for a very long time, probably since 4965. As a consequence, the field is always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense. Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and all the code for it.

2015-06-03iwlwifi: prepare for higher API/CAPA bitsJohannes Berg1-4/+4
Currently, loading the firmware fails when it has higher API or CAPA bits than the driver supports. That's an issue with integration. At the same time, actually using api[0] and capa[0] will become confusing when we also have api[1] and capa[1], and it's almost certain that we'll mix up the bits and use the bits for api[1] with api[0] by accident. Avoid all this by translating the API/CAPA bits to the regular kernel test_bit() format, and also providing wrapper functions. Also use the __bitwise__ facility of sparse to check that we're testing the right one.

2015-04-02iwlwifi: mvm: always reconfigure last MCC on initArik Nemtsov1-5/+4
Currently the last found MCC is reconfigured only in the recovery flow. But it should always be used when available, for the ifdown/up or RF-Kill/CT-Kill scenarios. While at it, fix a couple of bugs in the init-from-last-MCC flow. Return an error value when a current MCC is not found. Pass on the regdomain to cfg80211 only if it was changed and don't ignore the return value from the cfg80211-setter function.

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.
