This function is called by a device driver’s NetDev_Init() to configure a specific network device’s general-purpose input/ouput (GPIO) on a specific interface such as SPI, external interrupt, power & reset pins.

Prototype
Note that since NetDev_WiFi_CfgGPIO() is accessed only by function pointer via a BSP interface structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.
Arguments
p_if
Pointer to specific interface to configure device’s GPIO.
p_err
Pointer to variable that will receive the return error code from this function:
NET_DEV_ERR_NONE
NET_DEV_ERR_FAULT
This is not an exclusive list of return errors and specific network device’s or device BSP functions may return any other specific errors as required.
Returned Value
None.
Required Configuration
None.
Notes / Warnings
Since each network device requires a unique NetDev_WiFi_CfgGPIO(), it is recommended that each device’s NetDev_WiFi_CfgGPIO() function be named using the following convention:
NetDev_WiFi_[Device] _CfgGPIO[Number]()
[Device]
Network device name or type, e.g. RS9110 (optional if the development board does not support multiple devices)
[Number]
Network device number for each specific instance of device (optional if the development board does not support multiple instances of the specific device)
For example, the NetDev_WiFi_CfgGPIO() function for the #2 RS9110 wireless device should be named NetDev_WiFi_RS9110_CfgGPIO2(), or NetDev_WiFI_RS9110_CfgGPIO_2() with additional underscore optional.
