Btw, how is it supposed to work without header split capabale hardware?

I do not see header splitting as a requirement, let the raw
headers sit in the user queue and provide an offset to the data.
All of this page alignment stuff is unnecessary complexity.

I know you think applications are too dumb to be expected to handle
these kinds of things, but how many apps do you expect to convert over
to these new interfaces?

The ones that matter will, and great care will be made by the
programmer who does this.

Ugh, so it will not ring buffer of data _flow_, but ring buffer of
(header+data) packets.

Definitely, userspace application must be very smart to deal with 
ip/tcp/option headers...
