.It Cm burst
Enable packet bursting.
Packet bursting is a transmission technique whereby the wireless
medium is acquired once to send multiple frames and the interframe
spacing is reduced.
This technique can significantly increase throughput by reducing
transmission overhead.
Packet bursting is supported by the 802.11e QoS specification
and some devices that do not support QoS may still be capable.
By default packet bursting is enabled if a device is capable
of doing it.
To disable packet bursting, use
.Fl burst .

Set the desired channels to use when scanning for access
points, neighbors in an IBSS network, or looking for unoccupied
