This it the way I understood it as well.

OK. I can try it.

Hmm... I'm neither author of this part of the core nor irda expert, so I
can tell you what I can read from the source. It is done using
IrDA sockets (AF_IRDA). The follwing code may tell you something:
                peer.sir_family = AF_IRDA;
                peer.sir_lsap_sel = LSAP_ANY;
                peer.sir_addr = daddr;
                strcpy(peer.sir_name, "Nokia:PhoNet");
