Not really, since such a version was never in our I4L CVS and never
released by isdn4linux. It was my fault that this wrong temporary
attempt to solve the filtering problem was pushed into the kernel.
The new version is still compatible to the old filtering using
DLT_PPP (with libpcap 0.7x version) with was the previous version.
The DLT_LINUX_SLL solution did break compatibility and was rejected
because of this for PPP, but I did miss to revert the ISDN kernel
part in time, so it simple do not work today.
