pub unsafe extern "C" fn MSS_MAC_cfg_struct_def_init(
cfg: *mut mss_mac_cfg_t,
)Expand description
//** The MSS_MAC_cfg_struct_def_init() function initializes a mss_mac_cfg_t configuration data structure to default values. The default configuration uses the NULL_PHY interface connected to a PHY at address 0x00 which is set to auto-negotiate at all available speeds up to 1000Mbps. This default configuration can then be used as parameter to MSS_MAC_init(). Typically, the default configuration would be modified to suit the application before being passed to MSS_MAC_init().
@param cfg This parameter is a pointer to an mss_mac_cfg_t data structure that will be used as parameter to function MSS_MAC_init().
@return This function does not return a value.
Example: The example below demonstrates the use of the MSS_MAC_cfg_struct_def_init() function. It retrieves the default MAC configuration and modifies it to connect through a VSC8757 SGMII Ethernet PHY at MII management interface address 0x01. This example also demonstrates how to assign the device’s MAC address and force a 100Mbps full duplex link. @code mss_mac_cfg_t mac_config;
MSS_MAC_cfg_struct_def_init(&mac_config);
