Subject: [spp] [PATCH 10/29] tools/sppc: version checker for container DPDK ver
Date: Tue, 25 Feb 2020 19:34:27 +0900
Message-ID: <20200225103446.8243-11-yasufum.o@gmail.com> (raw)
In-Reply-To: <20200225103446.8243-1-yasufum.o@gmail.com>

You need to check version of DPDK on a container because some of
application might be deprecated or removed from some specific version.
For instance, load balancer example app was removed after v19.08-rc.

This update is to add methods for getting DPDK version from container,
and comparing it with expected version.
