Hi, With the current design, occasionally we are seeing issues where minstrel sends 3x3 rates for our 2x2 chip. IMHO, couple of things can cause this 1) update_caps doesn't take local HW capabilities in to account 2) While calculating sample_idx, we use MCS_GROUP_RATES which can cause a sampling hole. For eg: if sample_idx: 78, group will be 7 it is HT so rate_idx will be : 8 + (2-1) * 8 = 16 = 3x3 MCS0 20 MHz. ideally we should add a) local hw_checks and update groups.supported accordingly. b) use the formula index % get_max_group_rates (or) replace all instances of MCS_GROUP_RATES for HT with 8. (in set_rate, get_sampling_rate etc..) -- Thanks, Regards, Chaitanya T K. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
