SVN rev 192868 on 2009-05-27 01:45:23Z by adrian
Add in some INVARIANT checks in the TX mbuf descriptor "freelist" management code.
Slot 0 must always remain "free" and be a pointer to the first free entry in the
mbuf descriptor list. It is thus an error to have code allocate or push slot 0
back into the list.
