Subject: [dpdk-dev] [PATCH v3 4/6] net/virtio: store IO port info locally
Date: Fri,  6 Jan 2017 18:16:18 +0800	[thread overview]
Message-ID: <1483697780-12088-5-git-send-email-yuanhan.liu@linux.intel.com> (raw)
In-Reply-To: <1483697780-12088-1-git-send-email-yuanhan.liu@linux.intel.com>

Like vtpci_ops, the rte_pci_ioport has to store in local memory. This
is basically for the rte_pci_device field is allocated from process
local memory, but not from shared memory.
