网卡驱动方式

转载：[拨号PPP NDIS RNDIS CDC ECM NCM QMI_WWAN GOBINET RMNET MBIM概念介绍]
1、其实总结起来，我觉得就两种，一种是PPP类，一种是NDIS族类。NDIS族类的方式是标准化加高效化，对上，尽量标准化为网络设备；对下，则尽可能适应物理通道，高效利用。
2、RMNET拨号、QMI拨号、NDIS拨号都是NDIS拨号，叫法不同而已。
3、USB网卡拨号分为RMNET/QMI/NDIS、ECM、MBIM、RNDIS四种类型。
5、速度、对比、选用
  PPP使用复杂，对CPU负载大，网速上不去，不推荐使用。
  NDIS拨号支持QMAP功能，可以实现IP聚合和IP复用功能。支持IP聚合就可以一次URB传输多个IP包，减少CPU负载率。支持IP复用，可以实现多网卡的功能。因此推荐使用（尤其是高通模组）。
  ECM不支持IP聚合和复用功能，决定了不适用于高速场景。
  RNDIS协议上是支持IP聚合的，但是Linux自带驱动没有使用，所以也不适用于高速场景。
  MBIM默认就支持IP聚合，也支持IP复用。推荐使用。

EC200A 支持的网卡驱动 PPP ， ECM与RNDIS
EC20 支持PPP，QMI， GobiNet
RG500 支持 MBIM/RNDIS/ECM/NCM 四中网卡驱动，不推荐使用ppp

移远模组EC200A相关驱动文件

移远4G模组驱动移植（其实移远都已经修改驱动文件）

USB转串口驱动移植

首先匹配openwrt Linux的内核版本和移远驱动手册的Linux内核版本的高低，进行openwrt的USB驱动的Linux适配修改
openwrt 内核版本（make kernel_menuconfig 或者 /build_dir/linux-ar71xx_generic/linux-3.3.8）

Quectel_Linux_USB_Serial_Option_Driver_20210205.tgz 里面最相近的V3.3.1 可以模仿修改（直接相近的文件覆盖openwrt内核文件build_dir/linux-ar71xx_generic/linux-3.3.8/drivers/usb/serial/）

添加对应的 VID 和 PID

build_dir/linux-ar71xx_generic/linux-3.3.8/drivers/usb/serial/option.c 查找usb_device_id位置进行修改

方式一 ppp 拨号

cat4 理论值：150Mpbs 实际手机设备在30~50Mpbs 但ppp方式只实现8-10Mpbs

ppp通用性较强效率不高

添加上面驱动，编译然后烧录，启动后查看是否读取USB驱动

进阶方式移植EC200A

概述

由于build_dir 在make clean 后就会清空修改后文件，可以通过patch方式来实现编译自动生成代码，生成patch方式很多种。我倾向于验证后通过ubuntu自带工具diff 生成patch文件

OpenWrt移植EC200A驱动

环境说明：openwrt版本 18.06 硬件mtk7628 —> 内核版本：linux-4.14.206

需要编译一次make V=s -j8(才会产生 build_dir 目录)

将 build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/linux-4.14.206/drivers/usb/serial目录下option.c qcserial.c usb_wwan.c usb-wwan.h 拷贝到桌面(如果修改这部分代码，需要还原一下文件，最好方式make clean 然后再make V=s -j8)
