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
