Timestamp tx packets using a HW micro-second timer. This timestamp will be compared to the current timestamp in the hardware and if the difference is greater than 500ms, the packet will be dropped. Signed-off-by:

This is in preparation to support life time expiry of packets in the hardware to avoid head-of-line blocking where a slow client can hog a tx queue and affect the traffic to a faster client from the same queue. Time stamp the packets in driver to allow dropping them in the hardware if they are queued for more than 500ms. If queues are stopped, packets will be queued up outside the driver. Since we will be able to timestamp the packets only after they hit the driver, the timestamp will be less accurate since we cannot consider the time the packets spent in queues outside the driver. With this commit, to achieve accurate timestamping, the tx queues will not be stopped in normal conditions. The only scenarios where the queues will be stopped are when firmware commands are executing or if the interface is brought down. Now, we need to be prepared for a situation where packets hit the driver even after the tx queues are full. Drop all such packets in the driver itself. Signed-off-by:

My commit 3598e177 "iwlwifi: fix enqueue hcmd race conditions" move hcmd callback after command queue reclaim, to avoid call it with hcmd_lock. But since queue read index was updated, cmd data can be overwritten. Fix problem by calling callback before taking hcmd_lock and queue reclaim. Signed-off-by:

Default min_msk on my 0x4312 is 0x80000CBB, not 0xCBB. Now we follow specs and wl (noticed in MMIO dumps). Signed-off-by:

This variable is only ever checked right after the function that sets it, but the same function will also return the status, so we can pass it through instead of checking hw_ready later. Signed-off-by:

On new hardware, ucode images always come in pairs: code and data. Therefore, combine the variables into an appropriate struct and use that when both code and data are needed. Also, combine allocation and copying so that we have less code in total. Signed-off-by:

The current firmware loading mechanism in iwlwifi is very hard to follow, and thus hard to maintain. To make it easier, make the firmware loading synchronous. For now, as a side effect, this removes a number of retry possibilities we had. It isn't typical for this to fail, but if it does happen we restart from scratch which this also makes easier to do should it be necessary. Signed-off-by:

When the firmware encounters an error while the driver is waiting for a notification, it will never get that notification. Therefore, instead of timing out, bail out on errors when waiting for notifications. Signed-off-by:

We're unlikely to care about the actual time spent waiting, so make the function return an error code which is less error prone in coding new uses. Also, while at it, mark __must_check. Signed-off-by:
