[ale] Higher MTU for 40 GB NICs?

[Lightner, Jeffrey]

Is there any intrinsic benefit to using a higher MTU for 40 GB NICs?

That is, with all other things being equal is there any benefit to setting it higher on a 40 GB than on a 10 GB or 1 GB?

I notice 40 GB defaulted to 1500 just like the 1 GB and 10 GB.

The only time I've mucked with MTU in recent memory was because a vendor insisted it would solve a problem.   (It didn't because the issue wasn't networking in the first place but that is another story.)
