We need to carry frame_count through multiple calls of walk function
to account correctly for --num <pkts>. Also, move socket stats printing
into rx ring, since it belongs there.
Todo: the kernel socket seems to have a different count that what we
see. This needs to be fixed one way or the other. Not yet sure what's
causing this.

Prepare TPACKET_V3 for allowing to transparently setting up the
frame structure such that we do not need to change much in the
netsniff-ng/trafgen code.

There's no good reason why we currently waste an 'int' for
jumbo_support while this must better be done as 'bool'.

Prepare setup_rx_ring_layout for both, v2 and v3. Also do some checks
during compile time if offsets stay the same as we operate on different
union mappings.

We decided to get rid of the old Git history and start a new one for
several reasons:
*) Allow / enforce only high-quality commits (which was not the case
for many commits in the history), have a policy that is more close
to the one from the Linux kernel. With high quality commits, we
mean code that is logically split into commits and commit messages
that are signed-off and have a proper subject and message body.
We do not allow automatic Github merges anymore, since they are
total bullshit. However, we will either cherry-pick your patches
or pull them manually.
*) The old archive was about ~27MB for no particular good reason.
This basically derived from the bad decision that also some PDF
files where stored there. From this moment onwards, no binary
objects are allowed to be stored in this repository anymore.
The old archive is not wiped away from the Internet. You will still
be able to find it, e.g. on git.cryptoism.org etc.
