2009-07-10cfg80211: prohibit scanning the same channel more than onceJohannes Berg
It isn't very useful to scan the same channel more than once during a given scan, and some hardware (notably iwlwifi) can only scan a limited number of channels at a time. To prevent any overflows, simply disallow scanning any channel multiple times in a given scan command. This is a small change in the userspace ABI, but the only user, wpa_supplicant, never asks for a scan with the same frequency listed twice.

2009-07-10mac80211: push rx status into skb->cbJohannes Berg
Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-07-10iwmc3200wifi: cache keys when interface is downSamuel Ortiz
When the interface is down and one sets a WEP key from userspace, we should be able to simply cache it. Since that implies setting part of the profile's security settings, we now alloc/free the umac_profile at probe/remove time, and no longer at interface bring up/down time.
