1 load

加载下列驱动：

mem_manager
asf
qdf
ath_dfs
umac
ath_hal
ath_rate_atheros
hst_tx99
ath_dev
qca_da
qca_ol
ath_pktlog

/sys/class/net/wifi*/is_offload，指示该芯片是offload，还是direct attach。

如果wifi0和wifi1均是direct attach，则可以卸载offload驱动：

qca_ol

如果wifi0和wifi1均是offload，则可以卸载direct attach相关驱动：

qca_da

ath_dev

hst_tx99

ath_rate_atheros

ath_hal

2 unload

按相反的顺序卸载上述模块即可。

3 detect

会执行load，然后生成配置文件：
