    net: vlan: introduce skb_vlan_eth_hdr()

    Similar to skb_eth_hdr() introduced in commit 96cc4b69 ("macvlan: do
    not assume mac_header is set in macvlan_broadcast()"), let's introduce a
    skb_vlan_eth_hdr() helper which can be used in TX-only code paths to get
    to the VLAN header based on skb->data rather than based on the
    skb_mac_header(skb).

    We also consolidate the drivers that dereference skb->data to go through
    this helper.
