6.1-stable review patch. If anyone has any objections, please let me know.

From: Vladimir Oltean <vladimir.oltean@xxxxxxx>
[ Upstream commit eabb1494c9f20362ae53a9991481a1523be4f4b7 ]
skb_mac_header() will no longer be available in the TX path when
reverting commit 6d1ccff62780 ("net: reset mac header in
dev_start_xmit()"). As preparation for that, let's use
skb_vlan_eth_hdr() to get to the VLAN header instead, which assumes it's
located at skb->data (assumption which holds true here).
