Sets up the specified rate masks.
Not passing any arguments would clear the existing mask (if any).
Commands that use the netdev ('dev') can also be given the
'wdev' instead to identify the device.
You can omit the 'phy' or 'dev' if the identification is unique,
e.g. "iw wlan0 info" or "iw phy0 info". (Don't when scripting.)
Do NOT screenscrape this tool, we don't consider its output stable.
