No really. My dirty hacking is just to comment out that part in dhcp.c.
Does this mean you removed the client identifier and dhcpd handed out
the same IP address when Linux booted?
Yes. That's true here.
Okay, it solved your problem.
Do you want to share the solution with us?
(in other words: Please, pretty please, post a patch )
Attached. It's not pretty, as I mentioned, it's a dirty hacking.
Actually I have no idea what will happen if it's used for Infiniband case.
However, with this modification, my client machine will only lease _ONE_
IP address from DHCP server. Before it leased 2 different ones.
