In the current driver, the MTU is set to the maximum value
capable for the backing device. This patch sets the MTU to the
default value for a Linux net device.

Why are you doing this?

What happens to users who depend upon the current behavior.

They will break, and that isn't acceptable.

The current behavior was already broken.  We were seeing firmware errors when sending jumbo sized packets .  We plan to add proper support for jumbo sized packets as soon as possible.  

Need to be explained, with a full detailed history of how things got this way,
in your commit message.
