Speaking of defaults, it would seem that the external 1.2.0 driver 
comes with 9000 bytes as the default MTU?  At least I think that is 
what I am seeing now that I've started looking more closely.

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.
