In practice, the only supported rates at least in mac80211 right now are DSSS: 1 2 CCK: 5.5 11 OFDM: 6 9 ... The supported preambles would be ERP and DSSS on 2.4 GHz, and OFDM (does that preamble even have a specific name?) on 5 GHz, I think. johannes --=-kNRDA2+wjOGH/I9Tc5jT Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJLe/DhAAoJEODzc/N7+QmaQUcQAKZu9/zlGwEOhzvGXBkXYVIl cmIh9dPTHjVnbNVresWgz1+w6LKaaMv8fvutuaGbbnE+mxoQipTVCeS0zYlU8hQS ayL/CwJQyeo60djIqWj+6cPPXk0EHqqipGrGsdTF2Zfez01jivgv5E2dTYdS03wq GKhWLoc87+U1HU2Bhtm8qDr3SvxhXn4zSbpnxLq8aPT1+VJlHoThnjdpAE7+HS/w 0x5XTc5ul++FoG3z1nsJyoQbR9+2V0IdAa2BSCw2D+1/l4buUo8nB5zquyGXq3j1 wbKG4SancYRWf/vPSJWieXRtVtJ7FhbhyPDpgVnmYn/tDCfPUz6gKnh2GeY88OWi bBPdHGInwkkA901AEm5LtjMFA4+NHaYHQRn1JKCIK2AxE8n7DoBL9c+HSzLy69WU fMCetzkKEd5e+Xoe3J+hi/ZvIDwCsER/AWaSC98CCgoJf6GhtryOsdaODYTnZcYB kJKhjEe9N/m1ChVLIOC7XP85gbmBGKtdxCjkG28rwUur6V7YB42Vve0ho38lT0/7 9H1qk1zp3q41nE9AMJH8NhZ3ONTku7vdLfY8475sXYUMyunKABpt/nuV5w3cDwMA +4QcS2pP/+4xhfPDpaHOrmOcWGeEBmOw+kr2EgR1UkICMd49UKF9y3P/P8Kmt0vT QVJ5zueeuoTPMhxWCJGv =gi6v -----END PGP SIGNATURE----- --=-kNRDA2+wjOGH/I9Tc5jT--
