Could you post a kernel-patch that fixes the worst problems with the
interfaces without breaking libpcap? I'm thinking of the timestamp
problem and the incomplete captures - so in case I want a complete
capture or better timestamps I could just apply your patch and rebuild
the kernel?

thanks

PS: OK, the timestamps have already been worked around and might not be
  doable withouth breaking the ABI but the capture thing should.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
