Routine Description:\r
 This is the SNP interface routine for converting a multicast IP address to\r
 a MAC address.\r
 This routine basically retrieves snp structure, checks the SNP state and\r
 calls the pxe_ip2mac routine to actually do the conversion\r
\r
Arguments:\r
  this  - context pointer\r
  IPv6  - flag to indicate if this is an ipv6 address\r
  IP    - multicast IP address\r
  MAC   - pointer to hold the return MAC address\r
