The following is an excerpt from iw's help page:

dev <devname> set monitor *
        Set monitor flags. Valid flags are:
        none:     no special flags
        fcsfail:  show frames with FCS errors
        control:  show control frames
        otherbss: show frames from other BSSes
        cook:     use cooked mode
        active:   use active mode (ACK incoming unicast packets)
        mumimo-groupid : use MUMIMO according to a group id
        mumimo-follow-mac : use MUMIMO according to a MAC address

What is "cooked mode" wifi monitoring?

    In general, Cooked mode means preprocessing of data before giving it to some program or system. So, iw must be activating some setting which gonna process first . Thoughe no idea, what exactly iw gonna processes here in this setting. – mkmayank May 15 '18 at 11:26
