Speaking of defaults, it would seem that the external 1.2.0 driver

That's the same for the in-kernel-tree code (9K MTU by default).
Assuming this is not wanted, I will submit a patch for that.
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.
