These are mutually exclusive: either you compile your kernel with tap or

You won't see any network interface in /dev; just run ifconfig -a and
check: you won't find any of the listed devices in /dev.
taps will come up when some programs activates it. Once you have openvpn
correctly running, you'll see tap0 in ifconfig's output and you'll be
able to run tcpdump against it.
