* mac80211: fix struct ieee80211_tx_queue_paramsJohannes Berg2008-07-14
| | | | | | | | | | | Multiple issues: - there are no "default" values needed - cw_min/cw_max can be larger than documented - restructure to decrease size - use get_unaligned_le16 Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: fix TX sequence numbersJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

* wext: make sysfs bits optional and deprecate themJohannes Berg2008-07-14
| | | | | | | | | | | The /sys/class/net/*/wireless/ direcory is, as far as I know, not used by anyone. Additionally, the same data is available via wext ioctls. Hence the sysfs files are pretty much useless. This patch makes them optional and schedules them for removal.

* mac80211: Fix ieee80211_rx_reorder_ampdu: ignore QoS null packetsEmmanuel Grumbach2008-07-14
| | | | | | | | | | | | This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.

* rt2x00: Reorganize beacon handlingIvo van Doorn2008-07-14
| | | | | | | | | | | | | | With the new beacon handling from mac80211 we can reorganize the beacon handling in rt2x00 as well. This patch will move the function to the TX handlers, and move all duplicate code into rt2x00queue.c. After this change the descriptor helper functions from rt2x00queue.c no longer need to be exported outside of rt2x00lib and can be declared static.

* mac80211: revamp beacon configurationJohannes Berg2008-07-14
| | | | | | | | | | | | | This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

* mac80211: make master netdev handling saneJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

* rt2x00: Fix NULL pointer error in adhoc/master modeIvo van Doorn2008-07-14
| | | | | | | | | | | | | | | As soon as an interface is enabled, and that interface is in adhoc or master mode, the device will start raising beacondone interrupts. But before the first interrupt is raised, mac80211 will probably not have send any beacons to the device yet, which results in a NULL pointer error when the skb is being freed. Note that the "raise beacondone interrupts without a beacon" is also a bug, and will be addressed later. The more important bug however is preventing the NULL pointer failt itself, since there might be other conditions that could trigger it as well.

* netdev: Create netdev_queue abstraction.David S. Miller2008-07-08
| | | | | | | | | | | | | | | | | | | A netdev_queue is an entity managed by a qdisc. Currently there is one RX and one TX queue, and a netdev_queue merely contains a backpointer to the net_device. The Qdisc struct is augmented with a netdev_queue pointer as well. Eventually the 'dev' Qdisc member will go away and we will have the resulting hierarchy: net_device --> netdev_queue --> Qdisc Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue pointer argument.

Maybe some other nasty things, but we caught only the oops in gc so far. The solution is to disarm the ifp->timer before flushing the rt from it.
