[02/13] net/mlx5: introduce hardware steering enable routine
Checks
Commit Message
As the new hardware steering operation will be implemented under the
new rte_flow_q APIs. This is not compatible with the existing rte_flow
PMD's Direct Rules flow operation routine.
This commit introduces an extra dv_flow_en = 2 to specify the new flow
operation initialize routine.
