DESCRIPTION
The i4bing driver interfaces the
.Fx NetGraph subsystem with the isdn4bsd package. The driver just packs packets received from the NetGraph subsystem without anything appended or prepended into raw HDLC packets on the B channel and transfers them to a remote site. Packets received from the remote site are queued into the NetGraph subsystem.
In the case where a packet for a remote site arrives in the driver and no connection has been established yet, the driver communicates with the isdnd(8) daemon to establish a connection.
