mac address lookup

Hi all,

I need a function in the ARP/ethernet code which gives me the mac address
of a machine given its IP address. Is there any such function in the
kernel ?

The reason i need the function is because my device is not accessing the
neighbour tables directly. I tried tracing the 'ioctl' suggestion below,
but it wont work for me.

Regards,
Amit
