Then why do you use DHCP protocol in first place?
Serial interface is not Ethernet and have no MAC address.
You should better use some standard PPP software and assign IP to the board via PPP.

PPP will give you more less overhead and more speed then Ethernet over serial emulation.
It also supports transparent compression of IP packets that would be benefit for low-speed serial interface.
