Do you mean we will now automatically establish LAPB connections without upper layers instructing us to do so?
Yes, as soon as the physical link is established, the L2 and also the L3 layer (restart handshake) is established. In this context I also noticed that I should add another patch to this patch-set to correct the restart handling. As already mentioned I have a stack of fixes and extensions lying around that I would like to get upstream.
If that is the case, is the one-byte header for instructing the LAPB layer to connect / disconnect no longer needed?
The one-byte header is still needed to signal the status of the LAPB connection to the upper layer.
