Si señor, hay un elemento IBSS

/conf/wifi/pseudo-ibss.click


Buscando por alli me encontre con esto:
https://pdos.csail.mit.edu/pipermail/roofnet/2007-January/001414.html

"pseudo-IBSS is not the only requirement.

The major requirement is multirate broadcasting which is allowed by
the atheros headers."

También encontre algo raro.

Si se fijan, los valores al ejecutar #read_handler.pl srcr/es.bcast_stats
son distintos a los que obtenemos nosotros y se repiten los rates con 2
valores distintos.
