Hi Stephen,

I can't reproduce the error, I think it is not broken, that issue should
be already fixed with commit [1].

Thanks for the report, not everyone is working with latest kernel, so
these reports are useful.

v16.11, can you please double check the DPDK version.

     kni: fix build with kernel 4.9

     compile error:
       CC [M]  .../lib/librte_eal/linuxapp/kni/igb_main.o
     .../lib/librte_eal/linuxapp/kni/igb_main.c:2317:21:
     error: initialization from incompatible pointer type
             [-Werror=incompatible-pointer-types]
       .ndo_set_vf_vlan = igb_ndo_set_vf_vlan,
                          ^~~~~~~~~~~~~~~~~~~

     Linux kernel 4.9 updates API for ndo_set_vf_vlan:
     Linux: 79aab093a0b5 ("net: Update API for VF vlan protocol 802.1ad
support")

     Use new API for Linux kernels >= 4.9
