I guess it just slipped through the cracks but is there something amiss with it ? Do I need to resend it maybe ? Thanks,

When an AP is configured for HT operation on 40MHz but has overlapping BSS on the secondary channel, it will fallback to 20MHz only. Also a 40MHz AP will downgrade to 20MHz while at least 1 40MHz intolerant STA is connected. However in the current code, on such an AP, we do not check the obss_interval parameter on the last 40MHz intolerant STA disconnect & start a timer that will unconditionnaly bring the AP to 40MHz operation even if it had overlapping BSS.
