[dpdk-dev] [PATCH] [v1 1/1] examples/kni: fix SIGTERM signal handling

[<vattunuru@marvell.com>]

From: Vamsi Attunuru <vattunuru@marvell.com>

Current KNI example application is not handling SIGTERM
signal when application is killed without passing any
specific signal in kill command.

Patch uses the existing signal handler for SIGTERM as well
for graceful application exit.

Fixes: 13c4ebd65a77 ("examples: minor changes")
