First of all, Martin is right. The commit in my staging tree should
fix the MTU issue but I don't have the hardware to test it on my own.

So far you never mentioned which board you have. Hence it's quite
difficult to have a look at the code about what could be wrong. It
would be helpful if you can name the last working revision to limit
the number of commits to look at.

Your best bet is to attach the/a serial console and check the console
for errors.
