Comment # 1 on bug 9838 from
That's a WinPcap bug - "protochain" requires looping, and no kernel
implementation of BPF supports looping (so that you can't force the BPF
interpreter in the kernel to go into an infinite loop), so either
libpcap/WinPcap shouldn't even try to install a "protochain" filter program
into the kernel or should try it, detect the failure, note that the failure
probably means "the kernel doesn't support this filter", and silently fall back
on running the filter program in userland.
