Welcome to the forums.

I'm not familiar with iwpriv, but you can also set the tx_chainmask and rx_chainmask using the method indicated here.

Re: How to use the command 'iwpriv'?

There is no problem, the message is fully correct - there aren't any private ioctls. Wireless extensions, which are based on ioctls, are deprecated. Drivers nowadays use netlink, not wext. Which means iwpriv is an outdated tool.
The only reason iwconfig and iwlist still work is because of a wext compatibility layer in the netlink-based wireless stack, but this layer won't be around forever.

Thks very much!!
By the way ,is there any other ways replaced the iwpriv?
If i'm going to configure the Radio layer,such as enable/disable transmit AMPDU aggregation(it can be configured by iwpriv"iwpriv wifiN AMPDU 1|0"),
and the tx/rx_chainmask can be set by the command"iwpriv athN tx/rx_chainmask mask"...what shall i do?
i think the iwpriv command is really powerful,what a pity~
