ipfilter is blocking connections because of not known change after 6th August

[Matthew Dillon]

    All right, I believe I have fixed the problem.  ipfilter was making 
    assumptions as to the value of TCPS_CLOSED which no longer hold (it's 0
    in FreeBSD but not 0 in DragonFly).  This prevented the tcp keep state
    entry from being properly initialized.
