Oh, now I understand what you meant: an additional helper API, and not a
replacement for the proposal.
I do not like it, because the resulting packet is not a real packet and
therefore needs to be handled very carefully. Handling that in the API would
require quite a few checks, and that still would not prevent the application
from doing things that are legitimate with a real packet but completely
broken with that kind of pseudo packet. But if the use is completely
optional this is not a blocking issue.
And, unless I am mistaken, deciding on this issue is not blocking for this
patch series (except maybe #2).
