Currently, configuration of DPDK parameters is done via the command line through a --dpdk **OPTIONS** -- command line argument. This has a number of challenges, including: * It must be the first option passed to ovs-vswitchd * It breaks from the way most other things are configured in OVS * It doesn't allow an easy way to populate defaults
This series brings the following changes to openvswitch: * All DPDK options are taken from the ovs database rather than the command line * DPDK lcores are optionally auto-assigned to a single core based on the bridge coremask. * Updated documentation v2: * Dropped the vhost-user socket configuration options. Those can be re-added as an extension * Incorporated feedback from Kevin Traynor. v3: * Went back to a global dpdk-init * Language cleanup and various minor fixes v4: * Added a way to pass arbitrary eal arguments v5: * Restore the socket-mem default, and fix up the ovs-dev.py script, along with the manpage for ovsdb-server v6: * Correct a documentation issue with INSTALL.DPDK.md * Correct a non-dpdk enabled OVS incorrect warning variable * Remove an excess whitespace v7: * After testing by Christian with dpdk-alloc-mem v8: * Confirmed ``make check`` operation with and without dpdk.
