This script doesn't look to be using any bash specific features to me,
so a better fix might be to change it to use /bin/sh rather than
requiring bash itself. [Needs testing, to check there isn't something
bash-specific hidden away, obviously]

Not sure having this linux-specific is a problem for dpdk-setup.sh,
since I don't think large parts of that script work with BSD anyway,
e.g. it assumes a linux hugetlbfs filesystem for hugepage setup. Not
that there is any harm in making the change you suggest either.
