xen: import xenvirt pmd and vhost_xen This provides a para-virtualization packet switching solution, based on the Xen hypervisor’s Grant Table, which provides simple and fast packet switching capability between guest domains and host domain based on MAC address or VLAN tag. This solution is comprised of two components; a Poll Mode Driver (PMD) as the front end in the guest domain and a switching back end in the host domain. XenStore is used to exchange configure information between the PMD front end and switching back end, including grant reference IDs for shared Virtio RX/TX rings, MAC address, device state, and so on. The front end PMD can be found in the Intel DPDK directory lib/ librte_pmd_xenvirt and back end example in examples/vhost_xen. Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>

mempool: rename object constructor typedef This commit renames mempool_obj_ctor_t as mempool_obj_cb_t. In next commits, we will add the ability to populate the mempool and iterate through objects using the same function. We will use the same callback type for that. As the callback is not a constructor anymore, rename it into rte_mempool_obj_cb_t. The rte_mempool_obj_iter_t that was used to iterate over objects will be removed in next commits. No functional change. In this commit, the API is preserved through a compat typedef. Signed-off-by: Olivier Matz <olivier.matz@6wind.com>
