 Except of FreeBSD's packet reassembly is broken for long
 time.
 For example, http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/167603

NFS has been broken since the beginning of time.  NFS has always
had problems sending segments > the packet size.

There are a lot of ISPs that load balance multiple feeds
so OOO packets are a normal occurrence. A stack that doesn't 
handle out of order tcp packets doesn't work in today's world.
