I think thats the best solution for -net.  I would then try to come up
with a version that follows your "shrink gso_size" suggestion for -next.

Note that I mentioned this MTU thing months ago, and the bug is here
since years. I do not think its a very urgent matter :)

Fair enough.  I'll see that I have something ready when -next opens.

Thanks Eric.
