Just as clarification: This should not be relevant for your problem. It was 
just observed that the ELP [0] documentation talks about more padding. The 
underlying driver is usually only adding extra padding when required (e.g. 60 
bytes ethernet).


More relevant here would be whether the duration in the RTS/CTS frames look 
odd. Or what else prevents the devices in your six node setup from sending 
between each other.

Kind regards,
