So I am sure Rich would have = noted that. I think we need a bit of testing of the auto-tuning feature = and then make auto the default for ingest and egress. But for the = current users I did not want to change the default without some testing = (my track record of breaking things slightly comes to mind ;) ) Once we get the calculation correct, I would vote for the default being = "auto" (that is, the ingress and egress strings would be pre-configure = to "auto"). It would be the right thing for virtually anyone, but people = could change it in the name of research. While I'm lobbying, I would still like to see the second item in the = Link Layer choices be "Ethernet with overhead" (instead of simply = "Ethernet') Doing this makes it easier to explain: "None" means none. CeroWrt does not make any per-packet adjustments at = all. "Ethernet with overhead" means that CeroWrt assumes that each packet has = an additional overhead of N bytes that needs to be taken into account. "ATM: ..." means that CeroWrt accounts for the incredibly arcane = (stupid?) vagaries of the ATM 48-in-53 byte framing. Thanks. Rich=
