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
