These patches are good.  I just have a few nits to point out for future
reference.

This is fine for now, but since this is networking code, in the future
could you write your declarations in reverse Christmas tree order?

	short asdfasd;
	shortest i;

Please don't do unrelated white space changes in their own patches.
