> Subject: [PATCH 04/28] net/ice/base: change dummy packets with VLAN
>
> Ethertype was traded as VLAN tpid in dummy packets with VLAN.
> This led to a problem when user wanted to add filter for VLAN and
> ethertype.
>
> Change ice_vlan_hdr to reflect correct order of VLAN fields in
> packets (VLAN tpid, VLAN id). Correct all dummy packets with VLAN.
> Move VLAN fields before ethertype and change offsets. Leave values
> from dummy packets unchanged as they fit to new VLAN layout.
>
> Order of offsets in ice_prot_ext_tbl_entry for VLAN protocol should
> reflect order of fields in ice_vlan_hdr. However, hardware doesn't
> support matching on all tpid. This should be done by matching on
> packet flags. There is no FV word with protocol for VLAN and offset
> 2. Because of that, adding vlan tpid with not zero mask will lead
> to error in creating recipe.
