Subject: examples/ethtool: close port before exit
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=497025dac0aff87693557687e0a37f7342aa2ce4

examples/ethtool: close port before exit

Currently, ethtool directly ends the process after 'quit' cmd. In this
case, software resources are not released and hardware resources of the
device are not uninstalled.

This patch adds closing port operation to release resources.
