Getting remote_id during DHCPACK in dhcp.c?

Hi All, new here...

I'm trying to get my hands on the remote_id at the time the DHCP lease 
is acknowledged.  Are either of these two routes feasible?
1) lease->state->interface_info->remote_id
2) use lease->state->packet and dig through the packet options?

I'm trying to record a Cable Modem's MAC when a CPE requests an IP.  For 
instance, in the following scenario, I want to get the CPE's MAC and the 
CM's MAC.

ISP........Cable Modem (CM).........CPE (i.e. laptop)

When the laptop requests an IP, I need to record the CPE MAC and the 
CM's MAC for legal purposes.

Doing this when the code in dhcp.c acknowledges the DHCPACK seems most 
appropriate as it's logging everything but the CM's MAC.

Thanks for pointers!!  Oh, fwiw, I'm using v3.0.7 which seemed most 
current.  Should I be using 4.xx?

Thanks,

Bret
