mt7601在linux4.1.15上的移植
在b-link拿到一份代码，他们在linux4.4的内核上正常编译运行，代码在如下链接
https://download.csdn.net/download/bgk112358/10441975
用到仪表Linux4.1.15时就编译不通过了
修复和移植步骤如下
1 在mt7601_JEDI_v1.9/Makefile修改编译选项
#PLATFORM = PC
PLATFORM = IMX6DQ
----------------------------------------------
ifeq ($(PLATFORM),IMX6DQ)
LINUX_SRC = /home/dell/work/sc01_1/GS4/linux-imx/
# CROSS_COMPILE= /opt/fsl-imx-fb/4.1.15-2.0.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-
endif
------------------------------------------------
CROSS_COMPILE会在SDK的脚本里加到环境变量中
2. 此时编译会出现大量这一类的警告
在mt7601_JEDI_v1.9/os/linux/config.mk加入如下编译参数
ifeq ($(PLATFORM),IMX6DQ)
EXTRA_CFLAGS := $(WFLAGS) -D__KERNEL__ -DMODULE -fno-pic -Wno-error=date-time
endif
-----------------------------------------
遇到这种错误就使用如下参数，macro "__TIME__" might prevent reproducible builds [-Werror=date-time]
Wno-error=date-time 不把该行为当成错误
-Wno-date-time 不把该行为当成警告
向gcc传递-fno-pic显式指定我们不希望PIC（位置无关代码），此代码无需这个参数
3. 此时编译会出现未定义的宏
4. 在linux的官方的提交的patch有说明
From: Johannes Berg
This is really just duplicating the list of information that's
already available in the nl80211 attribute, so remove the list.
Two small changes are needed:
* remove STATION_INFO_ASSOC_REQ_IES complete, but the length
(assoc_req_ies_len) can be used instead
* add NL80211_STA_INFO_RX_DROP_MISC which exists internally
but not in nl80211 yet
This gets rid of the duplicate maintenance of the two lists.
这个宏变量是一个重复的变量，恰好在Linux3.14.28有在Linux4.1.15中没有，既然一个重复的不影响功能的变量，我们就删掉他
在代码中出错的地方，就是用或者不用变量STATION_INFO_ASSOC_REQ_IES，既然用不用都行，我们就不用他，将KERNEL_VERSION改为小于我们当前Linux4.1.15
5. 这一个编译错误已经通过了，但是还有很多的编译错误，未定义变量
这个未定义变量中STATION开头的变量都能在如下patch中找到替代的变量，也都是可以通过修改makefile中的KERNEL_VERSION来选择

6. 将报错的地方全都用KERNEL_VERSION来选择可用的变量再编译，Bingo，编译成功
7. 将代码合并到yocto上，直接合并到内核里（在下一篇文章）
8. 使用架构是mt6701+hostapd
下载一个hostapd，并交叉编译hostapd和它所依赖的两个库，libnl和ssl，在yocto有直接的recipe
9. 打开ap热点
hostapd apd.conf -B
apd.conf配置如下

wpa=2
driver=nl80211
ignore_broadcast_ssid=0
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP10. 打开dhcp，系统自带udhcpd，没有的话自行编译一个
udhcpd dhcp.conf
dhcp.conf配置如下
