Automatically Add Clients With Following DHCP Vendor IDs:
Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID
(option 60). The local DHCP server will decline and send the requests to a remote
DHCP server by mapping the appropriate LAN interface. This will be turned on when
Interface Grouping is enabled.
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is
for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are
ETH1, ETH2, ETH3, and ETH4.
