/**
This is the SNP interface routine for converting a multicast IP address to
a MAC address.
This routine basically retrieves snp structure, checks the SNP state and
calls the pxe_ip2mac routine to actually do the conversion
Converts a multicast IP address to a multicast HW MAC address.
This function converts a multicast IP address to a multicast HW MAC address
for all packet transactions. If the mapping is accepted, then EFI_SUCCESS will
be returned.
@param this context pointer
@param IPv6 flag to indicate if this is an ipv6 address
@param IP multicast IP address
@param MAC pointer to hold the return MAC address
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
@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 Simple Network Protocol interface has not
been started by calling Start().
@retval EFI_INVALID_PARAMETER IP is NULL.
@retval EFI_INVALID_PARAMETER MAC is NULL.
@retval EFI_INVALID_PARAMETER IP does not point to a valid IPv4 or IPv6
multicast address.
@retval EFI_DEVICE_ERROR The Simple Network Protocol interface has not
been initialized by calling Initialize().
@retval EFI_UNSUPPORTED IPv6 is TRUE and the implementation does not
support IPv6 multicast to MAC address conversion.
