The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at.
