At least in minstrel_ht_get_tp_avg() I don't see it: On the other hand, if the channel were fully utilized then this should likely, indirectly reduce the average transmission success probability a bit. So in that case I guess congestion / channel utilization could indirectly be factored in. But still if a channel is 90% utilized / has 90% airtime usage then this wouldn't mean that the expected throughput from Minstrel will be about 90% lower compared to an fully free channel, I guess?
