I'm not familiar with ixgbe but this issue reminds me of this thread [1],
particularly the following comment:

 "the rte_flow_error returned was not very useful for it does return the
 error of the last tried filter-type (L2 tunnel in ixgbe), and not the error
 of the filter-type that my setup should use (flow director)"

CC'ing Wenzhuo, I think this issue is present in 17.02, has it been fixed
since?
