Remy Horton bda68ab9d1 examples/ethtool: add user-space ethtool sample application
Further enhancements to the userspace ethtool implementation that was
submitted in 2.1 and packaged as a self-contained sample application.
Implements an rte_ethtool shim layer based on rte_ethdev API, along
with a command prompt driven demonstration application.
