使用树莓派3B打造超强路由之二：初成

通过第一篇《使用树莓派3B打造超强路由之一：初装》的努力，树莓派3B已经可以作为一台超低能耗、随身携带的开发用服务器来使用了。但这对于目标——打造超强路由而言，才刚刚开始。接下来，我们需要将其打磨成一台基本的无线路由器。

新款的树莓派3B功能之丰富，性能之强悍，让我垂涎。考虑到家里的网件 WNDR3700v2 也服役四年有余了。还是败了一个树莓派3B回来打造成新的路由。

	/**
	* Base contract that all upgradeable contracts should use.
	*
	* Contracts implementing this interface are all called using delegatecall from
	* a dispatcher. As a result, the _sizes and _dest variables are shared with the
	* dispatcher contract, which allows the called contract to update these at will.
	*
	* _sizes is a map of function signatures to return value sizes. Due to EVM
	* limitations, these need to be populated by the target contract, so the
	* dispatcher knows how many bytes of data to return from called functions.
