DPDK: upgrade to 17.11.2 LTS. Changes: 1. This version is downloaded from https://fast.dpdk.org/rel/dpdk-17.11.2.tar.xz. 2. Adapt the new interface `rte_ring_dequeue_burst`. 3. Change the type of `port_id` from uint8_t to uint16_t. 4. Just link libdpdk.a instead of the other libaries. 5. Install libnuma-dev first. 6. Update the documents.

DPDK: upgrade to 17.11.2 LTS. Changes: 1. This version is downloaded from https://fast.dpdk.org/rel/dpdk-17.11.2.tar.xz. 2. Adapt the new interface `rte_ring_dequeue_burst`. 3. Change the type of `port_id` from uint8_t to uint16_t. 4. Just link libdpdk.a instead of the other libaries. 5. Install libnuma-dev first. 6. Update the documents.
