[dpdk-dev] [PATCH v1] librte_vhost: Add an abstraction to hide vhost-user and cuse devices.

This patch should be put on "lib/librte_vhost: vhost-user support" patch series written by Xie, Huawei. There are 2 type of vhost devices. One is cuse, the other is vhost-user. So far, one of them we can use. To use the other, DPDK is needed to be recompiled. The patch introduces

[dpdk-dev] [PATCH v6 12/13] eal/pci: Add rte_eal_dev_attach/detach() functions

These functions are used for attaching or detaching a port. When rte_eal_dev_attach() is called, the function tries to realize the device name as pci address. If this is done successfully, rte_eal_dev_attach() will attach physical device port. If not, attaches virtual devive port. When
