In existing implementation, using wild card VLAN item is not allowed.
A VLAN item in flow pattern must include VLAN ID (vid) value.
This obligation contradics the intention of documentation update [1].
This patch updates the VLAN item validation and translation, to allow
wild card VLAN item, without VLAN ID value.
User guide and release notes are updated accordingly.

Can you please refer to the commit in the repo, instead of a superseded patch in
patchwork?
