8.3 Wireless Configuration Utility

The device driver that supports the Cypress IEEE 802.11 family of wireless solutions provides an input/output control (IOCTL) interface for making advanced configuration

settings. The IOCTL interface makes it possible to make settings that are normally not possible when using just the native operating system-specific IEEE 802.11 configura-

tion mechanisms. The utility uses IOCTLs to query or set a number of different driver/chip operating properties.
