It is unclear how it will coexist with VLAN items in a pattern. Are you going to add consistency checks on ethdev-layer? Also it is unclear why both bit fields and a number are required. Referenced RFC lacks definition of S-VLAN anc C-VLAN in the context. Exact definition to avoid ambiguity. So, it looks required to modify the structure, but I'd not stick to referenced RFC, since the result could differ a lot. May be reference it as just an example.
