This will result in many layers bloating the image a little.

We could optimize it with approximately
[
  RUN export DEBIAN_FRONTEND=noninteractive && \
  eatmydata apt install -y --no-install-recommends \
    cscope \
    global \
    linux-headers-amd64 &&
  git clone https://github.com/luigirizzo/netmap.git /usr/src/netmap && \
  cd /usr/src/netmap && \
  git checkout v11.3 && \0
  cd LINUX && \
  ./configure --no-drivers --no-apps --kernel-dir=$(ls -d /usr/src/linux-headers-*-amd64) && \
  make install && \
  cd / && \
  rm -rf /usr/src/netmap &&
  eatmydata apt remove cscope global linux-headers-amd64

(untested)

Essentially this means we only add 1 layer to the docker image
and it only contains the final binary bits

Still, what you have is what already exists in tree, so on
that basis
