I do not think this should be part of the release notes as it is not a new
behavior introduced by a commit for 17.08. It has been the case since VLAN
support was added to the mlx5 rte_flow implementation back in 17.02.
Please move this info to guide/nics/mlx5.rst, the resulting documentation
commit should likely be CC'ed to stable at dpdk.org against "net/mlx5: support
VLAN flow item".
