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.
Changes:
Remove directory `ipc`, and add a new directory `compat`.
Directory `compat` includes some FreeBSD source files to be compatible
with Linux.
Port FreeBSD ifconfig to F-Stack.
This commit contains an ipc library implemented by dpdk rte_ring and
sysctl tool ported from FreeBSD.
With this commit we can get and set FreeBSD kernel state in runtime.
Because pkg-config(version before 0.28) reordered -Wl,--whole-archive -Wl,--no-whole-archive not to surround the dpdk libraries, so we remove pkg-config and do it ourselves.
