This function call is used to configure the Wi-Fi interface, including setting the SSID,
the mode, WEP keys, etc. It can also be used to get status information and to request a
Wi-Fi scan.
Note that the Wi-Fi interface must be down when you are using the following commands
that change the configuration — WIFI_SSID, WIFI_MULTI_DOMAIN, WIFI_
COUNTRY_SET, WIFI_MODE, WIFI_OWNCHAN, and WIFI_WEP_FLAG. The
wifi_ioctl() function description in the WIFI_WLN_API.LIB library provides
sample code to demonstrate how to bring down the Wi-Fi interface to change these
configurations.

The cmd, data, and len parameters are described in detail below. Each cmd (command)
has different requirements for the data and len parameters. Note that these
are strings in all cases, even for “numeric” parameters.
