It looks like ubuntu has a patch on dhclient
("udp_checksum_offloading") which switches SOCK_PACKET to SOCK_RAW. As
near as I can tell this is the only place in the code base where it's
using SOCK_PACKET, so ubuntu's dhclient won't make sockets of this
type, which is why I've not seen this before. I've asked the guy who
applied the patch how long we'll carry it, but he's on vacation this
week. If he says we'll drop it soon, I'll see about adding SOCK_PACKET
support.
