Subject: [spp] [PATCH v2 12/12] spp_vf, spp_mirror: exclude vhosts at process initialization
Date: Wed, 25 Dec 2019 13:49:54 +0900 [thread overview]
Message-ID: <20191225044954.3600-13-oda@valinux.co.jp> (raw)
In-Reply-To: <20191225044954.3600-1-oda@valinux.co.jp>
A vhost device is shared among the primary process and secondary
processes. When a secodary process starts it recognizes vhost
devices if they are used by processes already started. It is not
appropriate to include to port information as PHY devices.
