While I like what that does for perrformance, and at the risk of putting words into the mouths of netdev, I suspect that 1500 bytes is indeed the desired default. It matches the IEEE specs, I've yet to see a switch which enabled "Jumbo Frames" by default, not everything out there even believes that Jubmo Frames means 9000 byte MTU etc etc etc. I think that 1500 bytes for an "Ethernet" device remains in line with the principle of least surprise. rick jones - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
