* mac80211: use rate index in TX controlJohannes Berg2008-05-21
| | | | | | | | | | | | | | | This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers. This mostly serves to reduce the TX control structure size to make it fit into skb->cb so that the fragmentation code can put it there and we can think about passing it to drivers that way in the future. The rt2x00 driver update was done by Ivo, thanks. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: let drivers wake but not start queuesJohannes Berg2008-05-21
| | | | | | | | | | | Having drivers start queues is just confusing, their ->start() callback can block and do whatever is necessary, so let mac80211 start queues and have drivers wake queues when necessary (to get packets flowing again right away.)

* mac80211: fix bugs in queue handling functionsJohannes Berg2008-05-21
| | | | | | | | | | | Commit 55c308c1315bc7267dbb88011c208fd743cdce31 ("mac80211: QoS related cleanups") introduced another bug, the queue handling functions that operate on all queues now only operated on the first queues, not the A-MPDU queues as expected.

| | | | | | | | | | | | | | | | | | The mesh_path_node_copy() can be called like this: mesh_path_add `- write_lock(&pathtbl_resize_lock); /* ! */ `- mesh_table_grow `- ->copy_node `- mesh_path_node_copy thus, the GFP_KERNEL is not suitable here. The acceptable fix, I suppose, is make this allocation GPF_ATOMIC - the mpath_node being allocated is 4 pointers, i.e. this allocation is small enough to survive even under a moderate memory pressure.

| | | | | | | | | | | | | | | | | | (This set applies OK without the previous one of 4 patches, but with some fuzz in the 7th one) The mesh_path_node_free() does so under hashwlock. But, this one is called 1. from mesh_path_add() after an old hash is hidden and synchronize_rcu() is calld 2. mesh_pathtbl_unregister(), when the module is being unloaded and no devices exist to mess with this hash.

* libertas: fix multicast filtering on eth and msh interfacesDavid Woodhouse2008-05-21
| | | | | | | | | | | | | | | | | | | | | We weren't properly handling multicast on the mesh interface. Fix that, which involves setting up the hardware to use the union of dev->mc_list for both eth%d and msh%d devices. This means we can't do it directly from ->set_multicast_list() because we'd need to lock the other device to read its list, and we can't do that because it might deadlock. So punt the actual work to keventd. Also, invoke the same when taking an interface down; for some reason the core calls ->set_multicast_list while IFF_UP is still set in dev->flags when we're taking it down, so its addresses don't get removed then. We also convert MAC_MULTICAST_ADR to a direct command while we're at it, removing one more entry from the big switch statement in the deprecated lbs_prepare_and_send_command() function.

Such bugs aren't entirely unlikely in future too, as we convert more code to stop using this function. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W.
