一、参考文档：
1. Failed to select rate control algorithm http://rt2x00.serialmonkey.com/phpBB-static/5/t-5066.html 2. Wireless not working with AR9285 wireless chip. https://forums.gentoo.org/viewtopic-p-7572800.html 
二、解决办法：
1. 参考：
CONFIG_MAC80211_RC_PID is not set
CONFIG_MAC80211_RC_MINSTREL is not set
2. make menuconfig
