It sounds like we should make either the kernel code or wpa_supplicant
(or both) to be able to learn the basic rates in an existing mesh and
adopt the current settings if there is no explicitly configured value in
the local configuration. It does not make much sense to me to fail join
a mesh due to something like this..
