- Converts a multicast IP address to a multicast HW MAC address.
-
- @param This The protocol instance pointer.
- @param IPv6 Set to TRUE if the multicast IP address is IPv6 [RFC 2460]. Set
- to FALSE if the multicast IP address is IPv4 [RFC 791].
- @param IP The multicast IP address that is to be converted to a multicast
- HW MAC address.
- @param MAC The multicast HW MAC address that is to be generated from IP.
-
- @retval EFI_SUCCESS The multicast IP address was mapped to the
- multicast HW MAC address.
- @retval EFI_NOT_STARTED The network interface has not been started.
- @retval EFI_BUFFER_TOO_SMALL The Statistics buffer was too small. The
- current buffer size needed to hold the
- statistics is returned in StatisticsSize.
- @retval EFI_INVALID_PARAMETER One or more of the parameters has an
- unsupported value.
- @retval EFI_DEVICE_ERROR The command could not be sent to the network
- interface.
- @retval EFI_UNSUPPORTED This function is not supported by the network
- interface.
