Thanks Michael, sorry for the delay in getting back to you.
The timeout mechanism should have kicked in, I wonder why that's not
happening. Oh, I see. We don't timeout when receiving packets at all for
EFI, which means we're totally susceptible to the slightest bit of
packet loss.
I constructed a testcase to simulate 50% packet loss and the changes in
6.02-pre5 mean we actually make forward progress now.
Could you try 6.02-pre5?
