Not seeing the value in portidx here, since if we process this as two
seperate interrupts, it always comes out as 0. And 0 is what we expect.
Knowing that we processed more than one completion event inside a single
tasklet?
Yes, but I know that is very unlikely. In all the traces I have laying
around here is is 546921 to 3 for port being zero. :)
Perhaps the fact can also be derived from the timestamps on trace events
but it would be a bit of a heuristics. Sounds safer to just report the
fact at source, but I can also remove it if you want.
