MAC adress is protocol independent, it's burned into each network 
card.

Code is code, wether for linux or not, more important is the 
question: What language???

Here is a Delphi example for Windows 95:

Type
 TGUID=record
  A,B:word;
  D,M,S:word;
  MAC:array[1..6] of byte;
 end;
function CoCreateGuid(var guid: TGUID): HResult; stdcall; far external
'ole32.dll';

procedure TForm1.FormCreate(Sender: TObject);
var
 g:TGUID;
 s:string;
 i:integer;
begin
 CoCreateGUID(g);
 s:=''; for i:=1 to 6 do s:=s+IntToHex(g.MAC[i],2);
 Label1.Caption:=s; // this is the network card MAC address
end;
