Revert "Add support for unaddressed port"

This implementation may expose a vulnerability where a malicious
user can sieze the opportunity of a time window where a port
may land unaddressed on a shared network, thus allowing him/her
to suck up all the tenant traffic he/she wants....oh the shivers.

This reverts commit d4c52b7f5a36a103a92bf9dcda7f371959112292.
