Error was simple logic:

if (ethdr != NULL)

Should have been 

if (ethdr == NULL)

I could not see the forest through the trees.

You cannot just send "to (ethernet) interfaces", because the hardware
would not know where to send it to once the packet *is* in the
interface. Don'tcha think?
You need a target for those, like MAC address.
