- Add a leaf node CTL_NET.PF_ROUTE.0.AF.NET_RT_DUMP.0.FIB.  This returns
  routing table with the specified FIB number, not td->td_proc->p_fibnum.

- Add check_namevarlist() to check if ${name}_var is reserved in
  rc.subr or not.

- Fix a bug in ipv6_prefix_IF.  It did not work with the 64-bit prefix
  notation like 2001:db8:1:1.

- Use eui64 flag in ifconfig(8) instead of network6_getladdr()[*] for
  interface indentifier part.

- Fix address range specification with ifconfig(8) options such as:

  * inet 192.0.2.1-10 netmask 255.255.255.0 (inet range spec + ifconfig options)
  * inet6 2001:db8:1::1-f prefixlen 60 (inet6 range spec + ifconfig options)

  If prefixlen or netmask option is specified with CIDR notation at
  the same time, the option is used.

-  Do not set ND6_IFF_ACCEPT_RTADV on if_bridge(4) interfaces when
   ipv6_enable=yes.

    PR: 168520 170096
    Submitted by: adrian, zec

    Fix multiple kernel panics when VIMAGE is enabled in the kernel.
    These fixes are based on patches submitted by Adrian Chadd and Marko Zec.

    (1)  Set curthread->td_vnet to vnet0 in device_probe_and_attach() just before calling
     device_attach().  This fixes multiple VIMAGE related kernel panics
     when trying to attach Bluetooth or USB Ethernet devices because
     curthread->td_vnet is NULL.

    (2)  Set curthread->td_vnet in if_detach().  This fixes kernel panics when detaching networking
         interfaces, especially USB Ethernet devices.

    (3)  Use VNET_DOMAIN_SET() in ng_btsocket.c

    (4)  In ng_unref_node() set curthread->td_vnet.  This fixes kernel panics
         when detaching Netgraph nodes.
