For example, if you have an extra FreeBSD kernel module, and want to
compile it into F-Stack, you can do it like this:
```
cd f-stack/lib
export "KMOD_SRCS=/your/kmod/path/a.c /your/kmod/path/b.c"
export "CONF_CFLAGS=-I/your/kmod/path"
make
```
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.
