8021q: fix mac_len recomputation in vlan_untag()
skb_reset_mac_len() relies on the value of the skb->network_header pointer, therefore we must wait for such pointer to be recalculated before computing the new mac_len value. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: David S. Miller <davem@davemloft.net>
