This patchset comes from an attempt to improve the ConnTracker
performance in OvS-DPDK when used as a firewall.
We focused on some aspects like the management of recirculated packets
and some function tuning.
Some of this changes may be a benefit also for cases other than the
connection tracker firewall, eg in usecases where there's more than
Re-ordered patches. As "Skip EMC lookup.." is
the main change, now it is the 1st in the series.
Rebased, measurements updated.
Patch "move pkt metadata init out..." is removed
because it was not adding the same benefit with
the latest head of master .
Added comments to "Use memcpy on dp_packet.."
Re-worked to address feedback/comments on the list.
Added patch "move pkt metadata init out..."
