I have access to the driver but not sure what to change. I want the kernel
not to do any arp on the interface, can I do that? I guess one way is to add
a static arp entry, but any other way? Anyway to tell the kernel just send
out the packet to the interface and the other end just pickup without
looking at the destination MAC address? How normally is a point to point
link interface configured?

Thanks a lot,
