网上搜索说是驱动问题，不能用 staging 目录里面的 rtl8188eu 驱动程序

Answer from Larry Finger, maintainer of derived work from Realtek:

Only very old hostapd is supported by the staging driver, and not very well.

Your best chance is to use the v5.2.2.4 branch pf http://github.com/lwfinger/rtl8188eu.git.

This driver uses cfg80211/nl80211 commands and supports the latest hostapd.

I just wonder, why that cleanup development is happening out-of-tree (having it mainline would be easier for users). UPDATE: out-of-tree code is that complex that it'd take years to get it in a shape. That unfortunately leads to out-of-tree driver.

这个驱动整到 linux-4.9 里面很多编译错误。

终于找到了，这个驱动在 Linux4.9 编译正常，试一试能不能运行。
