> Fragmented PTYPE matching requires setting the mask to the exact
> RTE_PTYPE_L4_FRAG value to avoid conflicts with other L4 types.
> Adding L2 or L3 types to the same mask should be allowed, but there is a check
> for the exact value for setting the definer.
> This prevents the fragmented packets from matching in case of L2/L3 mask is
> provided as well. Mask out L2/L3 types when setting L4_FRAG.
