Possible fix for (Re: Internet problem after recent rewrite of mbuf)

[Matthew Dillon]

    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.
