[ovs-dev] [RFC 0/3] dpdk: Unification/deprecation of DPDK EAL config knobs.

[Ilya Maximets]

This patch-set deprecates the usage of current configuration knobs for
DPDK EAL arguments:

  - dpdk-alloc-mem
  - dpdk-socket-mem
  - dpdk-socket-limit
  - dpdk-lcore-mask
  - dpdk-hugepage-dir
  - dpdk-extra

All above configuration options replaced with single 'dpdk-options'
which has same format as old 'dpdk-extra', i.e. just a string with
all the DPDK EAL arguments.

Rationale:  See the commit message of the patch #1.

This patch set contains 3 patches that describes some kind of the
deprecation process.

Patch 1: Introduces 'dpdk-options' and removes all the documentation
         about old configuration knobs. Users could still use an
         old interface, but the deprecation warning will be printed.
         In case 'dpdk-options' provided, values of old options
         will be ignored. New users will start using new 'dpdk-options'
         as this is the only documented way providing EAL arguments.

         This patch could be applied now.

Patch 2: Drops support of all the old configuration knobs. Values
         are always ignored now. Warning appears in case some of the
         old options detected in database.

         This could be applied after branching the 2.12.

Patch 3: Removes all the warnings and silently ignores all the old
         configuration knobs.

         This could be applied after branching the 2.13.

This allows to fully drop all the old options in a year.
