The scripts for building Backdraft is available at /env/ansible.
If you are using a Mellanox network interface card then first run
install_ofed.sh (or install OFED manaully). Dependancies can be installed
using install.sh. Finally some major sub-programs in this repository
(includeing the virtual switch) can be built using build_repo.sh.
This scripts were tested on Ubunutu 20.04 and
Mellanox Technologies MT28800 Family [ConnectX-5 Ex].
