Old topic, see the thread at: http://marc.info/?l=linux-netdev&m=126311212608318&w=2 I would prefer to just jack up the defaults a bit. My opinion is that just about any larger default value is reasonable, because if you enable IP autoconfig on the command line, you expect the link and device to be there and waiting a few extra seconds won't bother you.
