* mac80211: allow all interfaces types to handle RX action framesAndrey Yurovsky2008-11-011-8/+0
| | | | | | | | | | | Eliminate the vif.type check in ieee80211_rx_h_action. This check is unnecessary (these action frames can be handled by all interface types) and currently prevents, for example, AP interfaces from handling BACK action frames such as ADDBA and DELBA requests.

* mac80211: make use of regulatory tx power settings on change of tx powerLuis R. Rodriguez2008-11-011-12/+6
| | | | | | | | | | | | We do not know what max power to allow until a device is targeting a channel, therefore only allow changing tx power if a channel is defined. Also make use of the channel's max power setting as defined by regulatory rules before allowing the user to use the requested power setting. If the user asked us to figure it out we use the max allowed by regulatory. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* Add nl80211 commands to get and set o11s mesh networking parameterscolin@cozybit.com2008-11-015-21/+377
| | | | | | | | | | | | | | | | The two new commands are NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS.

Moved struct mesh_config from mac80211/ieee80211_i.h to net/cfg80211.h. nl80211_get_mesh_params and nl80211_set_mesh_params unpack the netlink messages and ask the driver to get or set the configuration.

* mac80211: inform userspace of probe/auth/assoc timeoutJohannes Berg2008-11-011-0/+3
| | | | | | | | | | | | | | | | | I noticed that when for some reason [1] the probe or auth times out, wpa_supplicant doesn't realise this and only tries the next AP when it runs into its own timeout, which is ten seconds, and that's quite long. Fix this by making mac80211 notify userspace that it didn't associate. [1] my wrt350n in mixed B/G/HT mode often runs into this, maybe it's because one of the antennas is broken off and for whatever reason it decides to use that antenna to transmit the response frames (auth, probe); I do see beacons fine so it's not totally broken.

* airo: Kill directly reference of netdev->privWang Chen2008-11-011-85/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. In this driver, I don't simply use netdev_priv() to replace netdev->priv. The reason is: Pointer netdev->priv was changed in this driver, but it shouldn't. Because the memory was allocated when alloc_netdev() and netdev->priv should always point to that memory. So I use netdev->ml_priv to replace netdev->priv. After replacing, both ai and ai->wifidev->ml_priv point to the same memory. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Cc: John W.
