As such, no, we don't have any plans to do new HARP work such as BPF. That being said, adding BPF at the IP level can be considered a trivial task... I think literally less than one dozen lines of code. What's harder, and I admit that I haven't been following the tcpdump et. al. discussions, is adding ATM support. That is, passing info such as VPI/VCI so that one could say, decode UNI messages as well as IP traffic. You could take a look at most any if_* driver with BPF and then look at /usr/src/sys/netatm/ipatm/{ipatm_input.c,ipatm_output.c}. -- Joseph Thomas E/Mail: jpt@networkcs.com Network Computing Services, Inc. jpt@magic.net 1200 Washington Ave So.
