Subject: [dpdk-dev] [PATCH v3 12/14] examples/vdpa: remove useless device count
Date: Fri, 26 Jun 2020 15:27:10 +0200
Message-ID: <20200626132712.1437673-13-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20200626132712.1437673-1-maxime.coquelin@redhat.com>

The VDPA example now uses the vDPA class iterator, so
knowing the number of available devices beforehand is
no longer needed.
