I am not really sure if I understood now. So far those channel/page
combinations are the same because we have no special "type" value in
wpan_phy, what we currently support is the "normal" (I think they name
it legacy devices) phy type (no UWB, sun phy, whatever) and as Channel
Assignments says that it does not apply for those PHY's I think it
there are channel/page combinations which are different according to
the PHY "type". However we don't support them and I think there might
be an upcoming type field in wpan_phy which might be set only once at
registration time.
