vxlan: use dev->needed_headroom instead of dev->hard_header_len
[ Upstream commit 2853af6a2ea1a8ed09b09dd4fb578e7f435e8d34 ]
When we mirror packets from a vxlan tunnel to other device,
the mirror device should see the same packets (that is, without
outer header). Because vxlan tunnel sets dev->hard_header_len,
tcf_mirred() resets mac header back to outer mac, the mirror device
actually sees packets with outer headers
Vxlan tunnel should set dev->needed_headroom instead of
dev->hard_header_len, like what other ip tunnels do. This fixes
the above problem.
