I booted with a kernel from HEAD (I grabbed one Kris built from 
zoo.freebsd.org, hopefully no strange things with it)


and I see the same problems.  Working with Kip last night, I added to 
the tcp_offload function


int
tcp_offload_connect(struct socket *so, struct sockaddr *nam)
{
         struct ifnet *ifp;
         struct toedev *tdev;
         struct rtentry *rt;
         int error;

         return (EINVAL);

and that eliminated the problem.
