This patch makes the following changes to flow rule actions: - List order now matters, they are redefined as performed first to last instead of "all simultaneously". - Repeated actions are now supported (e.g. specifying QUEUE multiple times now duplicates traffic among them). Previously only the last action of any given kind was taken into account. - No more distinction between terminating/non-terminating/meta actions. Flow rules themselves are now defined as always terminating unless a PASSTHRU action is specified. These changes alter the behavior of flow rules in corner cases in order to prepare the flow API for actions that modify traffic contents or properties (e.g. encapsulation, compression) and for which order matter when combined. Previously one would have to do so through multiple flow rules by combining PASSTRHU with priority levels, however this proved overly complex to implement at the PMD level, hence this simpler approach. This breaks ABI compatibility for the following public functions: - rte_flow_create() - rte_flow_validate() PMDs with rte_flow support are modified accordingly: - bnxt: no change, implementation already forbids multiple actions and does not support PASSTHRU. - e1000: no change, same as bnxt. - enic: modified to forbid redundant actions, no support for default drop. - failsafe: no change needed. - i40e: no change, implementation already forbids multiple actions. - ixgbe: same as i40e. - mlx4: modified to forbid multiple fate-deciding actions and drop when unspecified. - mlx5: same as mlx4, with other redundant actions also forbidden. - sfc: same as mlx4. - tap: implementation already complies with the new behavior except for the default pass-through modified as a default drop.
