OK, DLT_IPV4 is 228 and DLT_IPV6 is 229.

I used capital-V; if people would prefer a lower-case v (DLT_IPv4 and DLT_IPv6), let me know.

I also checked in changes to libpcap to generate code for them; they're generating an extra instruction that the 
optimizer is somehow not removing, but at least they're not bothering to check the link type/IP version number.

In addition, I checked in support for DLT_IPV4 and DLT_IPV6 in tcpdump.-
This is the tcpdump-workers list.
