Allow / Forbid Duplicate Rules Insertion

The new device argument 'allow_duplicate_pattern` is used to generate errors when duplicated rules are trying to be inserted. The new device argument could be set to either of the following values:

• 0: Prevent from inserting flow rules with the same pattern of rte_flow items in non-root tables.

• 1: Allow inserting rules with the same pattern items. By default, the PMD will set it to 1 to keep the previous behavior

Set it to 0 if forbid, for example:

            

            
-a <PCI_BDF>,allow_duplicate_pattern=0
