Hello,
I answer myself:
I've tried with ath5k-compatible card and it behaves like iwl3945.
It means that when fixed the bitrates with a single value, the card always use 
that bitrate ALSO for broadcast frames.

The iwl4965 doesn't behave this way.
Any suggestion on how to solve the problem?

Regards.
