            Bug ID: 1154
           Summary: RTE flow: Getting a conflict error even though the
                    rules doesn't have a conflict
           Product: DPDK
           Version: 22.07
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: lthammin@usc.edu
  Target Milestone: ---

I am configuring below two flows on i40e through VPP and am seeing errors
saying "Failed to create flow" and "i40e_flow_set_fdir_inset(): Conflict with
the first rule's input set" although I don't see any conflict between the
flows. Other combinations work good say if protocol is not 'any' (wildcard).
Let me know if I am doing it wrong or if it's a bug.

The 2 flows are:
1. type/pattern: src-ip 1.1.1.1 dst-ip 2.2.2.2 protocol any
   action: redirect-to-queue 0
2. type/pattern: src-ip 3.3.3.3 dst-ip 4.4.4.4 protocol icmp
   action: redirect-to-queue 1
