Routine Description: | |
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 | |
Arguments: | |
this - context pointer | |
IPv6 - flag to indicate if this is an ipv6 address | |
IP - multicast IP address | |
MAC - pointer to hold the return MAC address | |
Returns: | |
