automatic rate adaptation

the driver can override the TX rate selection on packet-by-packet basis.
If I have to do this, do I have to modify the hostAP driver or just
make a raw socket with prism 2 header ?
I am currently doing a "iwpriv txpower set" to do this. But would be
interested to know a faster/better implementation.
Any pointers would be helpful.
