Notes / Warnings
Anchor
NetDev_CfgClk() should configure and enable all required clocks for the network device. For example, on some devices it may be necessary to enable clock gating for an embedded Ethernet MAC as well as various GPIO modules in order to configure Ethernet Phy pins for (R)MII mode and interrupts.Since each network device requires a unique NetDev_WiFi_StartCfgClk(), it is recommended that each device’s NetDev_WiFi_StartCfgClk() function be named using the following convention:anchor
NetDev_WiFi_[Device]_StartCfgClk[Number]()
Anchor
[Device]Network device name or type, e.g.
...
MACB (optional if the development board does not support multiple devices)
Anchor
[Number]Network device number for each specific instance of device (optional if the development board does not support multiple instances of the specific device)

NetDev_WiFi_StartCfgClk() function for the #2 RS9110 wireless devie MACB Ethernet controller on an Atmel AT91SAM9263-EK should be named NetDev_WiFiMACB_RS9110_Start2CfgClk2(), or NetDev_WiFIMACB_RS9110_StartCfgClk_2() with additional underscore optional.
