.It Cm smps
Enable use of Static Spatial Multiplexing Power Save (SMPS)
when operating in 802.11n.
A station operating with Static SMPS maintains only a single
receive chain active (this can significantly reduce power consumption).
To disable SMPS use
.Fl smps .
.It Cm smpsdyn
Enable use of Dynamic Spatial Multiplexing Power Save (SMPS)
when operating in 802.11n.
A station operating with Dynamic SMPS maintains only a single
receive chain active but switches to multiple receive chains when it
receives an RTS frame (this can significantly reduce power consumption).
Note that stations cannot distinguish between RTS/CTS intended to
enable multiple receive chains and those used for other purposes.
To disable SMPS use
.Fl smps .
.It Cm ssid Ar ssid
Set the desired Service Set Identifier (aka network name).
The SSID is a string up to 32 characters
