As the full file needs to be clean-up to re-write all items/actions

PMD to start in isolated mode.

After this patch flow API will not be usable.

Using inner RSS by default for GRE leads to memory corruption as the

Fixing by enforcing the default RSS level to be outer. This much

Future optimization for out of the box RSS can be done on subsequent

struct rte_eth_dev_data *dev_data;

ethdev: add shared counter to flow API

Add rte_flow_action_count action data structure to enable shared
counters across multiple flows on a single port or across multiple
flows on multiple ports within the same switch domain. Also this enables
multiple count actions to be specified in a single flow action.

This patch also modifies the existing rte_flow_query API to take the
rte_flow_action structure as an input parameter instead of the
rte_flow_action_type enumeration to allow querying a specific action
from a flow rule when multiple actions of the same type are specified.

This patch also contains updates for the bonding, failsafe and mlx5 PMDs
and testpmd application which are affected by this API change.
