From: Rosemarie O'Riorden <rorio...@redhat.com> This change removes the automatic memory limit on start-up of OVS with DPDK. As DPDK supports dynamic memory allocation, there is no need to limit the amount of memory available, if not requested.
Currently, if socket-limit is not configured, it is set to the value of socket-mem. With this change, the user can decide to set it or have no memory limit.
