4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Vlad Yasevich <vyasevich@xxxxxxxxx> [ 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.
