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 ;) )

> "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.

	Okay, changed. Any other changes to the GUI text you would like to see? Just let me know :) 

Best Regards
