Oh yes. It just occurred to me there is huge problem with eIPoIB as currently presented in these patches. It breaks DHCPv4 the same way it breaks ARP, but DHCPv4 is not fixed up. I am stunned to to realize there has been so much push for a solution that doesn't even support dhcp. How can anyone possibly argue that eIPoIB works or is useful? I just can't imagine. Totally stunned, Eric
