2011-09-22iwlagn: remove the callback in host commandsEmmanuel Grumbach15-134/+157
Before this patch, the upper layer could register a callback for each host command. This mechanism allowed the upper layer to have different callbacks for the same command ID. In fact, it wasn't used and the rx_handlers is enough: same callback for all the command with a specific command ID. The iwl_send_add_station needs the access the command that was sent while handling the response (regardless if the command was sent in SYNC or ASYNC mode). So now, all the handlers receive the host command that was sent. This implies a change in the handler signature.

2011-09-22iwlagn: split remain-on-channelJohannes Berg3-49/+62
If we're associated and want to do P2P at the same time, the scan for remain-on-channel is currently limited to 80ms because of the way the device will behave in that case. Instead of doing that, split up the dwell times into little pieces. It will not actually be a single big dwell time then, but will be close enough. This improves robustness of P2P in such scenarios.

2011-09-20iwlagn: do not use interruptible waitsJohannes Berg5-13/+8
Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

2011-09-19iwlagn: unmap cmd queue's tfds as BIDIEmmanuel Grumbach3-6/+20
If the driver is unloaded while there is still a host command in flight, its tfd will be freed by iwl_tx_queue_free. This function is called for both types of queues: Tx queues and cmd queue. This didn't take in count the fact that in Tx queues, tfds are mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all TBs are mapped as BIDI. Hence, tx_queue_free unmapped the second (and higher) TB of each tfd in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI. This means that if a multi TFD is in flight while we unload the driver (which is quite unlikely but can happen), we will get the warning below. This patch fixes this.

The way we check if there is host command that should be reclaimed is way too complicated. We should have a clear indication from the fw. The fw is expected to set the SEQ_RX_FRAME bit if the frame was originated by the fw which indicates to the driver that there is no host command to free. Somehow, there seem to have been buggy fw out there, hence the very old comment. This code checks if we have still buggy fw out there.
