Notes:
- Test cipher CFB support just in case (i.e. OpenWrt disabled it)
- Added some inline notes, please feel free to modify or remove them.
- Sorry for my bad English
- If you want to compile for OpenWrt, please make sure this hunk[1] not exists.
- Only tested on ARM mamba (Linksys WRT1900AC v1), it works.
