2008-09-24iwlwifi: remove HT flags from RXON when not in HT anymoreEmmanuel Grumbach
This patch removes the HT flags from RXON when moving from HT to legacy. This avoids keeping those flags set and possibly miss configuring firmware. If we are configured in HT, fat channel: channel 1 above, and move later to legacy channel 11, we need to clear the FAT channel control flags in RXON. If we don't, the firmware will understand this as channel 11 above which is not possible due to regulatory constraints, leading to firmware crash.

2008-09-24mac80211: allow interface settings changes only when downJohannes Berg
We currently allow monitor flags changes and mesh ID changes when the interface is up, which can lead to trouble. Change it to only allow when down. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-09-24cfg80211: show interface typeJohannes Berg
This patch makes cfg80211 show the interface in the nl80211 information about a specific interface. API users are required to keep the type updated (everything else is fairly complicated) but you will get a warning if you fail to keep it updated.

2008-09-24mac80211: make master iface not wirelessJohannes Berg
There's no need to register the master netdev with cfg80211, in fact, this is quite dangerous and lead to having to add checks for the master interface all over the config handlers. This patch removes the "ieee80211_ptr" from the master iface in favour of having a small netdev_priv() associated with the master interface that stores the ieee80211_local pointer. Because of this, a lot of code in the configuration handlers can go away. To make this patch easier to verify I have also removed a number of wiphy_priv() calls in favour of getting the sdata first and then the local pointer from that.

2008-09-24cfg80211: fix regulatory code constJohannes Berg

2008-09-24cfg80211: clean up regulatory messJohannes Berg

2008-09-24cfg80211: fix static regdomainsJohannes Berg

2008-09-24wireless: Read scan flags correctly on x86-64David Kilroy
The SIOCSIWSCAN handler is passed data in an iw_point structure. Some drivers erronously use an iw_param instead. On 32 bit architectures the difference isn't noticed as the flags parameter tends to be the only one used by scan handlers and is at the same offset. On 64 bit architectures the pointer in the iw_point structure means the flag parameter is at different offsets in these structures. Thanks to Jean Tourrilhes for tracking this down for orinoco, and Pavel Roskin for confirming the fix and identifying other suspect handlers.

2008-09-23aoe: Fix OOPS after SKB queue changes.David S. Miller
Reported by Thomas Graf. If we don't unlink the SKB from the queue when we send it out in aoenet_xmit(), dev_hard_start_xmit() will see skb->next as non-NULL and interpret this to mean the SKB is part of a GSO segment list. Add __skb_unlink() call to fix that. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-23pkt_sched: Remove the tx queue state check in qdisc_run()Jarek Poplawski
The current check wrongly uses the state of one (currently the first) tx queue for all tx queues in case of non-default qdiscs. This check mainly prevented requeuing loop with __netif_schedule(), but now it's controlled inside __qdisc_run(), while dequeuing. The wrongness of this check was first noticed by Herbert Xu.

2008-09-22pkt_sched: Check the state of tx_queue in dequeue_skb()Jarek Poplawski

2008-09-22net: network device name ifalias supportStephen Hemminger
This patch add support for keeping an additional character alias associated with an network interface. This is useful for maintaining the SNMP ifAlias value which is a user defined value. Routers use this to hold information like which circuit or line it is connected to. It is just an arbitrary text label on the network device. There are two exposed interfaces with this patch, the value can be read/written either via netlink or sysfs. This could be maintained just by the snmp daemon, but it is more generally useful for other management tools, and the kernel is good place to act as an agreed upon interface to store it.
