Changes configured to operate in Channel 100(HT80), if bin5 chirp radar is injected at center frequency at 5530 MHz, instead of adding channel 108(HT20), it adds channel 116(HT20) of adjacent 80 MHz band to NOL list. We have the following variable assignments in function dfs_pulses_within_window: dfs->dfs_min_sidx = pl->pl_elems[*index].p_sidx dfs->dfs_max_sidx = pl->pl_elems[*index].p_sidx Since the variable pl->pl_elems[*index].p_sidx is of signed type and variables dfs->dfs_min_sidx/dfs->dfs_max_sidx are of unsigned type, if the value of the variable pl->pl_elems[*index].p_sidx is negative, the values of the variables dfs->dfs_min_sidx/dfs->dfs_max_sidx become very large unsigned value. When sidx is converted to frequency offset, the frequency offset also becomes very large and it is greater than 40Mhz(half of HT80). In this case, 50MHz is added to center frequency 5530 MHz, which becomes 5580MHz(channel 116(HT20)). This results in the channel 116(HT20) of adjacent 80 MHz band to be added to NOL list. Change the type of the variables dfs->dfs_min_sidx/dfs->dfs_max_sidx from unsigned to signed so that assignments do not alter the actual value of the frequency offset.
