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 is the only datapath feature in OVS to be configured on the command line
* It requires specialized knowledge of sub-component command switches
* It also inteprets non-EAL arguments (confusing users)
* It is a broken model.
This series brings the following changes to openvswitch:
* All DPDK options are taken from the ovs database rather than the
command line
* Non-EAL arguments also have separate database entries
* DPDK lcores are optionally auto-assigned to a single core based on the
bridge coremask.
* DPDK options have default behaviors
* 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.
Retested on live-host
v9:
* Cleanup of comments
* Cleanup of one place where headers are specified
* Mark the dpdk coremask and numa config as optional
* Added 5/6 to scan the extras and warn the user when conflicting
DB entries are present
* Acks given for all but patch 5/6
