Ok, I will modify it for pushing instead of pulling packets.

Can I assume that the data will arrive ordered by timestamps ? If not
then I have to use one data_queue and one samples_fifo per channel,
isn't that too much?

I am pretty positive you can assume that the packets will arrive
ordered by timestamp.  The host can easily pre-order the packets and
send them sequentially.  If any packet is out of order, I would assume
it should be evicted and dropped immediately.

Now, since the 32-bit number can only have a finite amount of time
before it rolls over, there should be a well defined way of defining
the beginning of an epoch or invalidating the "previous timestamp"
register that may be used to ensure time continuity.
