Because if not.. I agree with you. I think you should just have EAPOL frames go out at the lowest rate for now and then worry about experimenting with more interesting ways to make EAPOL / DHCP frames cheaper. It fixes a lot of problems in noisy areas. That hack was hiding around in various commercial drivers I've seen, and it's been in FreeBSD for a while. Same with DHCP traffic too - it's the second set of data frames that the rate control code sees, and it's the primary reason I dropped the initial sample rate down in FreeBSD so the DHCP exchange would have a better chance of succeeding after association. -adrian -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
