introduce '-2' commandline option for second BS-11
Using this option, you can use two BS-11 connected to the same E1
link. The first BS-11 needs to have BPORT0 and BPORT1 objects created with E1
Line Configuration attribute "multi-drop". The second BS-11 is configured with
only BPORT0 in star configuration, and needs to have the OML signalling on TS6
instead of TS1. Also, a kernel patch providing a second virtual E1 interface
is needed.
