Will resend using a better mail client. Just found out that web-gmail is no-go.

Just use git send-email, anything else is waste of time IMHO.

In mesh mode there is a race between establishing links and processing rates and capabilities in beacons. This is very noticeable with slow beacons (e.g. beacon intervals of 1s) and manifested for us as stations using minstrel when minstrel_ht should be used. Fixed by changing mesh_sta_info_init so that it always checks rates and such if it has not already done so.
