Configure DPDK options to isolate PMD cores and ovs process cores
The parameter -l in DPDK_OPTIONS is applied to both list cores to be used by PMD and the list of cores that all the OVS threads should run on. This will impact the DPDK performance, as cores on which PMD are running, should be completely isolated (no other process should) use it. For this, we are configuring, -l option with list of host cpus and the list PMD cores will be configured using ovs-vsctl config command.
