[ Upstream commit f654861569872d10dcb79d9d7ca219b316f94ff0 ]
skb_reorder_vlan_header is called after the vlan header has
been pulled. As a result the offset of the begining of
the mac header has been incrased by 4 bytes (VLAN_HLEN).
When moving the mac addresses, include this incrase in
the offset calcualation so that the mac addresses are
copied correctly.
Fixes: a6e18ff1117 (vlan: Fix untag operations of stacked vlans with REORDER_HEADER off)
