Oops 8) Seems, it should be reorganized to use single pointer
and to make xchg() (I still hope xchg() is atomic on pointers 8))
Will you fix it? I had to modify it a bit to make it useful
for anything but raw packet socket in any case.
Now it is fed with packets without IP headers for udp/tcp/raw,
and without ll headers for dgram, so that bpf is practically useless.
I can send you my local version tomorrow and will put new libpcap/tcpdump
to ftp.inr.ac.ru too.
