This series adds support offloading multiple "output"/"clone" actions within
one datapath flow.
Some cases which require sending a packet to multiple destinations is not
currently offloaded,
HWOL can be done by translating the fate actions "output" and "clone" into
rte_flow_action_sample actions
with ratio=1, this means 100% of the traffic will be mirrored.
Such datapath rules can be offloaded by embedding each non-last output/clone
action into an RTE_FLOW_ACTION_TYPE_SAMPLE with ratio=1.
Currently there are two types on mutiple destination outputs, forward to port
(local), or
encapsulate a packet and forward to a remote server (remote). Add support for
those cases
by having the sample action be either RTE_FLOW_ACTION_TYPE_PORT_ID for local
destinations, or
RTE_FLOW_ACTION_TYPE_RAW_ENCAP for remote destinations.
This patch is a rebased version of [1].
*V2:
