When processing 20/40 BSS Coexistence Management frames that do not explicitly require 40 MHz to be disabled, check whether the reported channels in 20/40 BSS Intolerant Channel Report element match the current primary channel. If so, allow 40 MHz operation to continue. This makes the during-operation updates for 20/40 Operation Permitted more consistent with the scans during initial BSS startup. The received 20/40 BSS Intolerant Channel Report channels are to be used in the OT set in the during-operation determination and the P == OT_i exception was ignored in the previous implementation which could result in the AP first starting with 40 MHz and then dropping to 20 MHz on first received 20/40 BSS Coexistence Management frame even though there was no change in the neighboring BSSs.
