We are having exactly the same problem. For us the aforementioned workaround doesn't seem to work and vector mode is always disabled with the i40e drivers. If I modify i40e_rxtx.c and exclude the stub functions using CONFIG_RTE_I40E_INC_VECTOR everything works as expected.
We are building DPDK with the CONFIG_RTE_BUILD_COMBINE_LIBS option enabled and link DPDK library to our application.
Any other ideas how this could be fixed?
