--- Comment #16 from Mark Johnston <markj@FreeBSD.org> ---
So we have a packet loop:

ip_output() at ip_output+0xce7/frame 0xfffffe00517c4610
vxlan_transmit() at vxlan_transmit+0x591/frame 0xfffffe00517c4720
ether_output_frame() at ether_output_frame+0xf9/frame 0xfffffe00517c4750
ether_output() at ether_output+0x6fb/frame 0xfffffe00517c47e0
ip_output() at ip_output+0x1355/frame 0xfffffe00517c48e0
vxlan_transmit() at vxlan_transmit+0x591/frame 0xfffffe00517c49f0
ether_output_frame() at ether_output_frame+0xf9/frame 0xfffffe00517c4a20
ether_output() at ether_output+0x6fb/frame 0xfffffe00517c4ab0
ip_output() at ip_output+0x1355/frame 0xfffffe00517c4bb0
...

I wonder if vxlan_transmit() should perhaps be calling
if_tunnel_check_nesting() somewhere?
