As far as I understand, the point is that it's no longer a 'solution' at the core, i.e. there is no replacement for hci_ldisc or any of these, just modules for the additional h4 protocols that don't have a linux implementation yet. The patch set that was originally posted here had a new framework, but after the comments from Alan and me, Par-Gunnar agreed to use the existing framework instead and extend it in a useful way. Please read all of the discussion we already had. You made a good point here, but I fear you had both Par-Gunnar and me confused because it was a point that already got resolved. Arnd
