无线命令iwpriv不论是在OpenWrt还是在各个无线芯片厂商的SDK中，都是标配，还有iwconfig , 由此可见掌握iwpriv的重要性。
下面看下在openwrt平台上其支持的参数。

列几个对我们有用的命令： stat
[email protected]:~# iwpriv ra0 stat
ra0 stat:
Tx success = 3727835
Tx retry count = 821419, PER=18.0%
Tx fail to Rcv ACK after retry = 270, PLR=0.00%
Rx success = 14461968
Rx with CRC = 10763575, PER=8.6%
Rx drop due to out of resource = 22
Rx duplicate frame = 2559
False CCA = 80442725
RSSI = -46 -52 0
Last RX Rate = MCS 7, 20M, LGI, MM
WPS Information:
Enrollee PinCode(ra0) 00000369
Enrollee PinCode(ra1) 00000376
Enrollee PinCode(ApCli0) 00000383
Ap Client WPS Profile Count = 0
最最重要的当属这里的 set命令，基本上所有的无线参数都可以通过set来设置。
后续的文章会对这个iwpriv再继续分析。
