Subject: [dpdk-dev] [PATCH v2 5/5] net/vdev_netvsc: add "force" parameter
Date: Fri, 22 Dec 2017 19:01:39 +0100 [thread overview]
Message-ID: <20171222173846.20731-6-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <20171222173846.20731-1-adrien.mazarguil@6wind.com>
This parameter allows specifying any non-NetVSC interface to use with tap
sub-devices for development purposes.

Same as ``iface`` except a suitable NetVSC interface is located using its
MAC address.
+- ``force`` [int]

+ If nonzero, forces the use of specified interfaces even if not detected as
+ NetVSC.
+
Not specifying either ``iface`` or ``mac`` makes this PMD attach itself to
all NetVSC interfaces found on the system.
