2. when we want to create socket by fstack, we code like this :
`s = ngx_socket(domain, type | SOCK_FSTACK , protocol);`

1. Add a new directive proxy_kernel_network_stack :
Syntax: proxy_kernel_network_stack on | off;
Default: proxy_kernel_network_stack off;
Context: http, stream, mail, server
This directive is available only when NGX_HAVE_FF_STACK is defined.
Determines whether proxy should go throught kernel network stack or fstack.
2.Update F-Stack_Nginx_APP_Guide.md

freebsd and linux have a different "struct sockaddr".
In ff_recvmsg and ff_recvmsg, ```msg->msg_name```,which can refer to address, can be expected to be converted .

1. Nginx based on fstack delays setting up server on fstack until ngx_worker_process_init. ngx_configure_listening_sockets should as well.
2. FStack does not support IP_PKTINFO

When nginx is configured like this:
```
server {
listen 8000;
kernel_network_stack on;
location / {
proxy_pass http://127.0.0.1:8080/;
}
}
```
nginx will crash, becasue kernel network stack is handled in a single thread, but we have hijacked all the socket apis, it causes that all apis enter to f-stack's path which is in main thread.

Note that this only fix the error, `divert` is still not usable, refer to #136.
If you want to use NAT, you can just use the built-in `ipfw nat`
instead.
