Just for clarification, in this case the DPDK application will work but will
only use RTE_MAX_LCORE cores, right? You need to compile to use all available cores.
Are cores more than RTE_MAX_LCORE usable after this patch?

+1 to remove limit in --lcores, but I didn't make it work with this patchset, I
may be missing something, I tried by setting the "RTE_MAX_LCORE=32", in this
case should '--lcores "(30-40)@(10-20)"' work?
