[ns] disabling RTS/CTS does not work - RTSThreshold_ 3000

[Patxi Azpiroz]

Dear NS users:
I'm pretty new in ns sorry if the question is too trivial but I can't
come with it.
I put Mac/802_11 set RTSThreshold_ 3000 to disable RTS/CTS been the
packe size 270.
After the simulation the trace file shows RTS/CTS packets. Why is it so?

I have seen this problen in the mailing list more than once but there
is no solution that works in my case.

Thanks,

Patxi.
