Don't use the interruptible variant of mutex_lock(). It doesn't really need to be interruptible. This avoids nasty error handling. Signed-off-by:

Some drivers (e.g. ath9k) assume that it's safe to go into low-power mode immediately after the idle state changes. To support that, mac80211 even calls drv_flush() before that happens. In some instances, mac80211 sent a packet right after recalculating the idle state, this patch fixes that. Signed-off-by:

Finding the group index for a specific rate is done by looping through all groups and returning if the correct one is found. This code is called for each tx'ed frame and thus it makes sense to reduce its runtime. Do this by calculating the group index by this formula based on the SGI and HT40 flags as well as the stream number: idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) + (SGI * MINSTREL_MAX_STREAMS) + (streams - 1) Hence, the groups are ordered by th HT40 flag first, then by the SGI flag and afterwards by the number of used streams. This should reduce the runtime of minstrel_ht_get_group_idx considerable. Signed-off-by:Helmut Schaa <helmut.schaa@googlemail.com> Acked-by:

The drivers are not required to fill in rate->count if rate->idx is set to -1. Hence, we should first check rate->idx before accessing rate->count. Signed-off-by:

The shared key authentication frame that needs to be encrypted (the third one in the shared key handshake) is directly encrypted in ieee80211_send_auth and the IEEE80211_TX_INTFL_DONT_ENCRYPT is set. All others are not encrypted, so the only way to get to this is erroneously on no-monitor AP side. Remove the special case for authentication frames to fix the AP shared key side when operating without cooked monitor interfaces -- with cooked monitor the IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we never get here -- an AP never encrypts auth frames. Without this patch, an AP operating in WEP mode with my no-monitor patches would erroneously encrypt all authentication frames, instead of none. Signed-off-by:
