[dpdk-dev,2/2] eal: make the -n argument optional
Commit Message
Obtaining the correct value of memory channels, especially from a
running system, can be anything from difficult to plain impossible.
Since the value is merely an optimization and does not affect functionality
otherwise, its pointless to force such a guess on users initially, such
things belong to performance tuning phase.
