Description of changes:
We have some debug sanity checks in the UDP socket
sendcode to make sure we're not wasting syscalls by sending empty packets (which are meaningless here). This code was triggering that in some of the testing I've been doing. This change, instead, checks if the packet is empty before calling it.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
