重载初始化脚本函数

可以通过如下方式覆盖这些标准的初始化脚本函数： {boot()}，boot时支持的命令，缺省为start。

Commands to be run at boot time. Defaults to {start()}

{restart()} 重启动服务，缺省为stop然后再start。 Restart your service. Defaults to {stop(); start()}

{reload()} 重新载入配置文件，缺省是restart。

Reload the configuration files for your service. Defaults to {restart()}

定制脚本命令

也可定制命令，创建功能函数，在EXTRA_COMMANDS变量中引用，Helptext添加在EXTRA_HELP中。

如下： status() {

# print the status info }

EXTRA_COMMANDS=\

EXTRA_HELP=\ status Print the status of the service\

在/etc/rc.common中可以看出，会包含此脚本，从而包含了其中的所有定义，从而可正确地去使用。

在openwrt中，所有无线的配置均通过iw命令来进行，如创建一个monitor 无线接口：iw phy phy0 interface add wd2j type monitor。

Iw的设备操作可通过mac80211.sh中查看及分析。通过iw phy0 info可查看硬件支持信息。

Iw命令行

具体参数如下：

iw说明

更多关于iw的说明参照如下链接：

http://wireless.kernel.org/en/users/Documentation/iw

nl80211是新的802.11 netlink接口，与cfg80211一起，目的是替换无线扩展部分。nl80211与cfg80211仍在开发中。

Iw则是基于nl80211的无线设备CLI配置工具，几乎所有新的驱动均支持并加到内核中了。

Iw也仍在开发中，帮助信息可参见http://wireless.kernel.org/en/users/Documentation/iw。

对于openwrt，未和原来的SDK一样使用iwconfig及iwpriv来设置无线参数，而是使
