Also, for bcm43xx this isn't a problem since the firmware (optionally but we use that afaik) takes care of not transmitting frames that are tagged for a different channel than currently tuned to. This is necessary because the packets travel through a FIFO and radio tuning is done by the driver without it knowing how much is still in the FIFO and a full disable is quite expensive (in terms of the time needed.) johannes --=-E/nGr83SxsRybs4nWpxv Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iD8DBQBFaWdU/ETPhpq3jKURAoumAJ0WMmCVcL4+xhEdUWTPcBr/zTMXsQCbBqOJ FnfY3weMJg+W70bRRV7Fgfw= =ZboS -----END PGP SIGNATURE----- --=-E/nGr83SxsRybs4nWpxv-- --===============0808883891== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev-0fE9KPoRgkgATYTw5x5z8w@public.gmane.org https://lists.berlios.de/mailman/listinfo/bcm43xx-dev --===============0808883891==--
