[ovs-dev] [PATCH v13 0/6] Convert DPDK configuration from command line to DB based

[Aaron Conole]

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 for datapath configuration.

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

This series has been build tested (including `make check`) on Fedora 23, OS X
Windows (via appveyor), and FreeBSD 10.3; the v13 has had very basic testing
applied (start, configure some of the settings).

A huge round of thanks on the work so far should be given to the following
folks (in alphabetical order):

* Christian Erhardt     (Testing)
* Daniele Di Proietto   (Reviews, general suggestions)
* Flavio Leitner        (Original efforts, reviews)
* Kevin Traynor         (Testing, general suggestions, reviews, doc reviews)
* Panu Matilainen       (Initialization ideas, eal arguments ideas, reviews)
* RobertX Wojciechowicz (Testing, general suggestions)
* Sean Mooney           (Testing, general suggestions)

v13:
* Rebased to latest upstream
* Addressed sparse errors
* Removed the dpdk-mem-channels option
* Switched to using the other_config smap directly.
* Moved the netdev_dpdk_register() to the dpdk_init__ routine.
