I don't recall the exact details right now, but I think it was a potential race (hence yes, you might not be able to trigger it) where some packets could be lost (and a retransmitt would happen). But again, it's been a long time since I thought about this one. -- Tom Rini http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
