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.
Since f-stack uses `rte_pktmbuf_clone` to copy mbuf to other lcores when dispatching arp packets, but it doesn't real copy the packet data. The buf_addr of pktmbuf is pointed to the same address.
The arp response packet is generated with the same mbuf from the request
packet, it just swaps the src and dst address, so the copied mbufs will also be changed.
What we need is a deep copy function, and the arp packets are really small, so deep copy will not harm performance too much.
Fix#53#111#112.
ipfw -- interface for firewall, packet scheduler, NAT and so on.
It is comprised of several components: the kernel firewall filter rule processor and its integrated packet accounting facility, the logging facility, NAT, a forward facility, a bridge facility, and an ipstealth facility.
Note that the `dummynet` traffic shaper is not merged.
In some cases, for example, packets are forwarded to your server through
IP tunnel, and they will be received on fixed queues, since RSS doesn't support tunnels.So we need to dispatch them again.
With this commit, we can implement a dispatcher callback function and regist
it, packets retrieved from rx queue will be dispatched again according to
the dispatcher result.
In current implementation, cores and ports are one to one mapped, this
PR allowed user to specify the core list used to handle single port. for
example cores 1,2,3 handle port 0 and cores 4,5,6 handle port 1.
- Add `port_list` config to dpdk section (used to specify the enabled port list)
- Add `lcore_list` config to port section(used to specify the core list mapped to that port)
- Delete `nb_ports` config in dpdk section
- Delete `port_mask` config in dpdk section
1.Close #22.
2.Configure the HW indirection table when initializing port.
3.Use several LSBs of the rss hash result according to reta_size when
calculating queue index.
The ring length of some NIC devices(e.g vmxnet3 ) should be
between 512-4096. We should change the TX_QUEUE_SIZE from 256 to 512
and make sure we can use the f-stack in vmxnet3.

Since f-stack run with polling mode, nginx will call gettimeofday every loop, and cost a lot.
With this commit, f-stack will update current timespec periodically in
ff_hardclock_job. And ff_gettimeofday will get this value.
In nginx, hijack gettimeofday to call ff_gettimeofday.
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.
RX: VLAN strip, CRC strip, IP/TCP/UDP checksum.
TX: IP/TCP/UDP checksum, TSO.
Note that TSO has a problem: when enable TSO,
F-Stack is much slower(Temporarily not resolved).
So TSO is disabled by default.
Edit config.ini to enable it.
