This allows the driver to use suitable values that map easily to whatever key table is used in the hardware/firmware. This is _not_ same as 802.11 key index (0..3) and no code should made such an assumption. Based on a quick search, I did not find any net/mac80211 code assigning key->conf.keyidx into hw_key_idx (or struct ieee80211_tx_control::key_idx). At least as far as the original design is concerned, hw_key_idx is controlled by the hardware driver and it is only an internal identifier for a specific hwaccel key. -- Jouni Malinen PGP id EFC895FA -- 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
