[dpdk-stable] patch 'usertools: check for lspci dependency' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/08/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

Subject: [PATCH] usertools: check for lspci dependency

[ upstream commit 1a5a9cb32a93da47fa6aa0da8407337feaf901f8 ]

On some distributions (such as CentOS 7) lspci may not be installed
by default, causing exceptions which are difficult to interpret.

Fix devbind script to check if lspci is installed at script startup.
