Compile libpcap with DLT_LINUX_SLL2

Hi Guy,

some time ago we did together DLT_LINUX_SLL2 support for libpcap.
I don't remember the details, but IMHO it was enabled by default.
When now I compile libpcap and tcpdump, it's still using DLT_LINUX_SLL:

tcpdump: listening on any, link-type LINUX_SLL (Linux cooked v1), ...

What do I do wrong?

Kind regards,
