The code that sets up the i2400m (firmware load and general driver setup after it) includes a couple of retry loops. The SDIO device sometimes can get in more complicated corners than the USB one (due to its interaction with other SDIO functions), that require trying a few more times. To solve that, without having a failing USB device taking longer to be considered dead, allow the retry counts to be specified by the bus-specific driver, which the general driver takes as a parameter.

When the TX FIFO filled up and i2400m_tx_new() failed to allocate a new TX message header, a missing check for said condition was causing a kernel oops when trying to dereference a NULL i2400m->tx_msg pointer.

i2400m_dev_shutdown() tried to reset the device to put it in a known state before shutting down. But that turned out to be pointless. We reach this case in two paths: 1 - when the device resets, to clean up state 2 - when the driver is unloaded, for the same however, in both cases it is pointless; in (1) the device is already reset, why do it again? in (2) we can't -- the USB stack, for example, doesn't allow communicating with the device when the driver is being unbound and if the device is disconnected, the device is gone already. So just remove it. Leave the function as a placeholder for future cleanups that will be done from data allocated by the driver during device operation.

i2400m_tx_skip_tail() needs to handle the special case of being called when the tail room that is left over in the FIFO is zero. This happens when a TX message header was opened at the very end of the FIFO (without payloads). The i2400m_tx_close() code already marked said TX message (header) to be skipped and this function should be doing nothing. It is called anyway because it is part of a common "corner case" path handling which takes care of more cases than only this one. The tail room computation was also improved to take care of the case when tx_in is at the end of the buffer boundary; tail_room has to be modded (%) to the buffer size. To do that in a single well-documented place, __i2400m_tx_tail_room() is introduced and used. Treat i2400m->tx_in == 0 as a corner case and handle it accordingly. Found and diagnosed by Cindy H. Kao.

In some situations, when a new TX message header is started, there might be no space for data payloads. In this case the message is left with zero payloads and the i2400m_tx_close() function has just to mark it as "to skip". If it tries to go ahead it will overwrite things because there is no space to add padding as defined by the bus-specific layer. This can cause buffer overruns and in some stress cases, panics.

Reported and fixed by Cindy H Kao. When the device is stopped __i2400m_dev_stop() stops the network queue. However, when this is done in the middle of heavy network operation, when the bus-specific subdriver is still wrapping up and it reports a sent TX transaction with _tx_msg_sent() right after the device was stopped, the queue was being started again, which was causing a stream of oopsen and finally a panic. In any case, said call has no place there. It's a left over from an early implementation that was discarded later on. Signed-off-by: NInaky Perez-Gonzalez <inaky@linux.intel.com>

The i2400m driver waits for the device to report being ready for entering power save before asking it to do so. This module parameter allows control of said operation; if disabled, the driver won't ask the device to enter power save mode. This is useful in setups where power saving is not so important or when the overhead imposed by network reentry after power save is not acceptable; by combining this with parameter 'idle_mode_disabled', the driver will always maintain both the connection and the device in active state.

rfkill currently requires a global lock within the rfkill_register() function, and holds that lock over calls to the set_block() methods. This means that we cannot hold a lock around rfkill_register() that we also require in set_block(), directly or indirectly. Fix cfg80211 to register rfkill outside the block locked by its global lock. Much of what cfg80211 does in the locked block doesn't need to be locked anyway.

We don't want to trigger moving between PS mode during scan, because then we will sometimes end up sending nullfunc frames during scan. We're supposed to only send one prior to scan and after scan. This fixes an oops which occured due to an assert in ath9k: http://marc.info/?l=linux-wireless&m=124277331319024 The assert was happening because the rate control algorithm figures it should find at least one valid dual stream or single stream rate. Since we allow mac80211 to send nullfunc frames during scan and dynamic PS was enabled at times we ended up trying to send nullfunc frames for the target sta on the wrong band for which we have no valid rate to communicate with it. This breaks the assumptions in rate control. We determine we also need to disable moving between PS modes when not associated so lets just add that now as well, and we should not have a ps_sdata when that interface cannot actually go into PS because it's not associated.

rfkill_set_global_sw_state() (previously rfkill_set_default()) will no longer be exported by the rewritten rfkill core. Instead, platform drivers which can provide persistent soft-rfkill state across power-down/reboot should indicate their initial state by calling rfkill_set_sw_state() before registration. Otherwise, they will be initialized to a default value during registration by a set_block call. We remove existing calls to rfkill_set_sw_state() which happen before registration, since these had no effect in the old model. If these drivers do have persistent state, the calls can be put back (subject to testing :-). This affects hp-wmi and acer-wmi. Drivers with persistent state will affect the global state only if rfkill-input is enabled. This is required, otherwise booting with wireless soft-blocked and pressing the wireless-toggle key once would have no apparent effect. This special case will be removed in future along with rfkill-input, in favour of a more flexible userspace daemon (see Documentation/feature-removal-schedule.txt). Now rfkill_global_states[n].def is only used to preserve global states over EPO, it is renamed to ".sav".

In order to handle powersave frames properly we had needed to pass these out to the device queues again, and introduce the skb->requeue bit. This, however, also has unnecessary overhead by needing to 'clean up' already tried frames, and this clean-up code is also buggy when software encryption is used. Instead of sending the frames via the master netdev queue again, simply put them into the pending queue. This also fixes a problem where frames for that particular station could be reordered when some were still on the software queues and older ones are re-injected into the software queue after them.
