This means that a merge of two HT40 networks with fixed channels will only take place if the HT40 configuration equals. - When merging, the looser will obey the winner's HT configuration if there is one. If not, keep the old one. - If HT has been configured through iw and a non-HT network is to be joined, iw's HT setting is used and announced. HT configuration within an IBSS may get inhomogeneous as a HT station may join from a non-HT beacon but there are other HT members. - When receiving a different HT configuration from another member of our BSSID, use this configuration (first beacon wins) Alex
