Function USBAX772AcceptMulticastList

USBAX772AcceptMulticastList defines multicast addresses an interface should receive:

int USBAX772AcceptMulticastList(int          DeviceIndex, 
                                int          Count, 
                                const BYTE * Addresses);

Parameters

DeviceIndex

Zero-based index of the AX772 interface.

Count

Number of multicast Ethernet addresses pointed to by parameter Addresses.

Addresses

Pointer to an array of multicast Ethernet addresses.

return value

RTU_SUCCESS or a negative error code on failure.

As long as this function has never been called or the last call specified zero for parameter Count, no multicast frames are received.

The current implementation merely supports receiving all or no multicasts. Once this function is called with Count > 0, all multicasts are received which may include frames the application is not interested in. The network stack must discard such frames.
