drivers do not include trailing 4-byte CRC values. For versions of Windows prior to Windows Vista, some packet analyzer applications such as Wildpackets' OmniPeek and TamoSoft's CommView for WiFi provide their own device drivers to support monitor mode. Linux's interfaces for 802.11 drivers support monitor mode and many drivers offer that support. STA drivers (Ralink, Broadcom) and every other manufacturer’s provided driver doesn’t support monitor mode. FreeBSD, NetBSD, OpenBSD, and DragonFly BSD also provide an interface for 802.11 drivers that supports monitor mode, and many drivers for those operating systems support monitor mode as well. In Mac OS X 10.4 and later releases, the drivers for AirPort Extreme network adapters allow the adapter to be put into monitor mode. Libpcap 1.0.0 and later provides an API to select monitor mode when capturing on those operating systems.
