Hi Mohammed,

thank you for having taken care of this. Is it possible to have more details
about this "impossibility"? I still have to understand, because on one side=
 we
all agreed on the fact that IBSS+AP coexistence will create problems on the=
 STA
(connected to the AP) because of the TSF jumps, but this would still "work"=
=2E On
the other side the maintainer is claiming this would not work at all :-) At=
 this
point, I'd like to clearly understand "why" he is claiming so: is it for the
same reason explained above (TSF jumps) or is there something else?

Cheers,
