Isnt it ARP ? i am providing an IP address as input and expect a MAC
address as output.
I went through the code in the kernel for ARP but i cant put my finger on
a fn that would provide this functionality to other routines.
arp_req_get() kind of does it but is defined as static in arp.c
I dont want to redo the whole thing.
Regards,
Amit
