[SPK] We have received suggestions from other IESG review we coming up with
text which will address this.

[SPK] Echo BFD to work we need destination IP address to be set to sending
VTEP address so that BFD packet is looped back when VTEP decapsulate VXLAN
header. Currently VTEP IP address may be used by tenant and hence this
needs more discussion and may need extension document. We have kept the
scope limited to async BFD for this document.
