Just curious:
Doesnt that change behaviour in the sense that __vlan_hwaccel_put_tag() now always adds VLAN_TAG_PRESENT to skb->vlan_tci, while before that change packet->vlan_tci may or may not had this flag?
In other words, should a variant of this patch be backported if it was a bug not not use __vlan_hwaccel_put_tag right from the start?
