    pfctl: match broadcast address behaviour to the kernel
    
    When using a /32 IPv4 interface address, pfctl(8) reports a 0.0.0.0
    as broadcast address.  The kernel does not consider this a broadcast
    address and ifconfig(8) has a check to exclude it.  Use the same
    check in pfctl(8).
