First of all thank you for your feedback. If anything else pops into
your mind please do not hesitate to share it.
We just had a quick internal discussion and we decided that we'll try to
come up with both options (callback and message queue).

Yes - I got your point first time. Remark above was not meant to imply
that "pull mode" is not a valid way (it is perfectly valid and probably
most often used in DPDK). I just noted that by staying at callback
level only one can still implement it.
But it is true that this way would impose more burden on the application
writer - so instead we now plan to provide both options.

We will. This is a definitely a good idea to work out things in "battle".
