pcap_inject() on loopback (FreeBSD)

Folks,

I'm trying to send an IPv6 packet with pcap_inject() on the loopback
interface of a FreeBSD 9.2 system.

What I write with pcap_inect() is the IPv6 packet, preceded with the
4-byte AF header (which I set to PF_INET6 (which is 28) in host byte order).

However, pcap_inject() fails with
"send: Address family not supported by protocol family"

and I also get this message on the console::
"looutput: af=31 unexpected"

which would seem to indicate that pcap_inject() is overwriting the value
I set with something else (pseudo_AF_HDRCMPLT?).

Any thoughts?

Thanks!

Best regards,
