iwlwifi: mvm: fix statistics variables type
When receiving statistics notification there is a field of average energy. This is defines as signed 8 bit, while FW refers to it as unsigned. when the energy is higher than 127 this causes in iwl_mvm_stat_iterator a wrong computation of the signal int sig = -stats->general.beacon_filter_average_energy; resulting in incorrect CQM event (change from low to high). While at it - update the rest of the fields to the correct type. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
