协议层下面是另外一个无关接口层，它将协议与具有很多各种不同功能的硬件设备连接在一起。
Below the protocols layer is another agnostic interface layer that connects protocols to a variety of hardware device drivers with varying capabilities.
然后是另外一个协议无关层，提供了与各个设备驱动程序通信的通用接口，最下面是设备驱动程序本身。
Next is another agnostic layer that permits a common interface to and from the individual device drivers that are available, followed at the end by the individual device drivers themselves.
最近，内核中引入了一种新的应用程序编程接口（NAPI），该接口允许驱动程序与设备无关层（dev）进行交互。
Recently, a new application program interface (NAPI) was introduced into the kernel to allow drivers to interface with the device agnostic layer (dev).
设备抽象层为上层应用程序提供了一套标准的、与设备无关的通信接口，并且通过文件描述表、设备描述表和驱动描述表建立了从通信接口到设备驱动的映射。
The device Abstract Layer provides a set of standard communication interface functions unrelated with specific device, which is mapped to device drivers by file table, device table and driver table.
