Subject: [dpdk-dev] [PATCH v1 02/13] bus/pci: add device matching field id
Date: Thu, 30 Aug 2018 15:41:53 +0200 [thread overview]
Message-ID: <826b5fdf55228723141a0d75d576a262c9759e5b.1535633784.git.gaetan.rivet@6wind.com> (raw)
In-Reply-To: <cover.1535633783.git.gaetan.rivet@6wind.com>
The PCI bus can now parse a matching field "id" as follows:
"bus=pci,id=0000:00:00.0"
or
"bus=pci,id=00:00.0"
