2008-02-29rt2x00: don't write past the end when writing short descriptors on rt61Adam Baker
The space allocated in the skb for a descriptor is only 24 bytes when setting up beacons in rt61 so make sure we don't write to the descriptor words beyond that and corrupt the beacon packet.

2008-02-29rt2x00: Queue handling overhaulIvo van Doorn
This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-02-29iwlwifi: enable 802.11n in KconfigTomas Winkler
This patch removes 'IWL4965_HT: depends on n' from iwlwifi's Kconfig 1. 11n is functional so no need to make it invisible in the configuration 2.

2008-02-29iwlwifi: A-MPDU Tx activation by load measuresRon Rindjunsky

Own __icmp(v6)_sk should be present in each namespace. So, it should be allocated dynamically. Though, alloc_percpu does not fit the case as it implies additional dereferrence for no bonus.

Overlay Routable Cryptographic Hash IDentifiers (RFC 4843, 2001:10::/28) are currenty not globally reachable.
