There is no need to send BSS changes to driver from beacons processed during scanning. We are more interested in beacons from an AP with which we are associated - these will still be used to send updates to driver as the beacons are received without scanning. This change·removes the requirement that bss_info_changed needs to be atomic. The beacons received during scanning are processed from a tasklet, but if we do not call bss_info_changed for these beacons there is no need for it to be atomic. This function (bss_info_changed) is called either from workqueue or ioctl in all other instances.

Some command structs contain reserved or unused fields, which the driver send uninitialized down to the card. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.

In rt2x00lib_intf_scheduled_iter() we use the hw->beacon_update() callback function. This means that it should behave similarly as mac80211 when that uses the function. This means that the skb should only be freed when beacon_update() has failed, otherwise the driver is the owner and is responsible for freeing the buffer.

The previous key locking patch left a small race: it would be possible to add a key and take the interface down before the key todo is run so that hwaccel for that key is enabled on an interface that is down. Avoid this by running the todo list when an interface is brought up or down. This patch also fixes a small bug: before this change, a few functions used the key list without the lock that protects it.

This change is necessary to allow cwnd to grow during persistent reordering. Cwnd moderation is applied when in the disorder state and an ack that fills the hole comes in. If the hole was greater than 3 packets, but less than tp->reordering, cwnd will shrink when it should not have. Signed-off-by: John Heffner <jheffner@napa.(none)> Signed-off-by: David S.

The alloc_netdev_mq() tries to produce 32-bytes alignment for both the net_device itself and its private data. The second alignment is achieved by adding the NETDEV_ALIGN_CONST to the whole size of the memory to be allocated. However, for those devices that do not need the private area, this addition just makes the net_device weight 1024 + 32 = 1068 bytes, i.e. consume twice as much memory. Since loopback device is such (sizeof_priv == 0 for it), and each net namespace creates one, this can save a noticeable amount of memory for kernel with net namespaces turned on. After this set the lo device is actually allocated from a size-1024 kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on.
