2008-08-01iwlwifi: don't stop queue in the middle of fragmented packetTomas Winkler
This patch avoids stopping queue in the middle of the fragmented packet. It is required that there will be ~10 (max packet/min fragment) or 16 (4 bits of frag number) free tfds all the time.

2008-07-29mac80211: partially fix skb->cb useJohannes Berg
This patch fixes mac80211 to not use the skb->cb over the queue step from virtual interfaces to the master. The patch also, for now, disables aggregation because that would still require requeuing, will fix that in a separate patch. There are two other places (software requeue and powersaving stations) where requeue can happen, but that is not currently used by any drivers/not possible to use respectively.

2008-07-14iwlwifi: fixes RTS / CTS supportEmmanuel Grumbach
This patch fixes the RTS / CTS support in iwlwifi. 5000 will send CTS to self when allowed by spec, 4965 will send RTS or CTS to self according to mac80211 request.

2008-06-30iwlwifi: setup compressed BA handlerEmmanuel Grumbach
This patch sets the compressed BA handler for 5000. This allows the rate scaling algorithm to take in count frames that were sent in AMPDUs. The compressed BA handler has been moved to iwl-rx.c since it is common to 4965 and 5000.

2008-06-14mac80211: remove ieee80211_get_morefragHarvey Harrison
Replaced by the new helper ieee80211_has_morefrags which is more consistent with the intent of the function. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-06-14mac80211: add helpers for frame control testingHarvey Harrison
A few general categories: 1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de in the same order as the fctl defines: A combined _has_a4 was also added to test when both FROMDS and TODS are set. 2) ieee80211_is_* is meant to test whether the frame control is of a certain ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres which also test a subset of the stype space. When testing for a particular stype applicable only to one ftype, functions like ieee80211_is_ack have been added. Note that the ftype is also being checked in these helpers. They have been added for all mgmt and ctl stypes in the same order as the STYPE defines. 3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl. The intel wireless drivers had helpers that used this namespace, convert the all to use the new helpers and remove the byteshifting as they were defined in cpu-order rather than little-endian.

2008-06-14iwlwifi: removing IWL4965_HT configRon Rindjunsky
This patch removes CONFIG_IWL4965_HT #ifdefs for iwl 4965 and 5000. 11n feature is stable in those drivers and its mode of operation is determined in mac80211, so this dependency is not needed any more.

2008-05-21mac80211: use multi-queue master netdeviceJohannes Berg
This patch updates mac80211 and drivers to be multi-queue aware and use that instead of the internal queue mapping. Also does a number of cleanups in various pieces of the code that fall out and reduces internal mac80211 state size. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21mac80211: move TX info into skb->cbJohannes Berg
This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

2008-05-21mac80211: use rate index in TX controlJohannes Berg
This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers. This mostly serves to reduce the TX control structure size to make it fit into skb->cb so that the fragmentation code can put it there and we can think about passing it to drivers that way in the future. The rt2x00 driver update was done by Ivo, thanks. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-05-21iwlwifi: clean up and bug fix for securityEmmanuel Grumbach
This patch cleans up code in security. 1) uses the new pointer to ieee80211_key_conf passed with the tx_control. 2) resolves bug reported by Mirco Tischler (sends ADD_STA in ASYNC mode) 3) resolves bug reported by Volker Braun regarding dynamic WEP 4) drops a WEP packet which has been garbaged by firmware. This can happen upon rekeying. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: John W.
