2011-11-17mac80211: Get rid of search loop for rate group indexHelmut Schaa
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: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-11-17mac80211: Check rate->idx before rate->countHelmut Schaa
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.

2011-11-17mac80211: remove crypto special case for auth framesJohannes Berg
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.

2011-11-11iwlagn: explicitly program P2P QoS parametersJohannes Berg
In P2P device mode, the device needs to have valid QoS parameters. We currently have those because we program parameters from any virtual interface into all contexts, but not only do we want to get rid of this -- it is also unpredictable since on the BSS context we might have any parameters, and there it might even be programmed for HT. Explicitly program default QoS parameters into the PAN context for P2P (the defaults are 11g but with QoS disabled) to make device behaviour predictable. This also helps when in a follow-up patch we will use TX QoS parameters from mac80211 only for the context they were meant for -- without this first that would completely break P2P device discovery.
