Possible fix for (Re: Internet problem after recent rewrite of mbuf)
Ok, I found a bug. It looks like the PPP code is stealing some flag
bugs from the MBUF's m_flags. The recent MBUF changes allocated more
flags and there is now a collision. (And for those programmers out
there, this code is a great example of how not to steal flags from
a system structure!).
Please try this patch.
