ifconfig not seeing IPv6 in x86 jail

Hi Guys

	I've just noticed this now, and I usually build jails (including x86 
jails for my x86 systems) for custom-building my base and ports, for 
pkg_add'ing later. It works great(!), and I've done this evar since 
we've been able to cross-build.

	It seems that ifconfig doesn't see the IPv6 address in an x86 jail ?

mars <at> spry832x86:~> sysctl security.jail.jailed
security.jail.jailed: 1

mars <at> spry832x86:~> ifconfig
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>
         ether 00:22:19:17:e5:9a
         inet 172.17.83.2 netmask 0xffffffff broadcast 172.17.83.2
         nd6 options=3<PERFORMNUD,ACCEPT_RTADV>
bge1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>
         ether 00:22:19:17:e5:9b
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
         options=3<RXCSUM,TXCSUM>

But I know I'm on IPv6:

mars <at> spry832x86:~> w
  8:28PM  up 8 days,  6:27, 1 user, load averages: 0.00, 0.00, 0.00

Re: ifconfig not seeing IPv6 in x86 jail

A PR sounds appropriate if it's not doing what it should. Just to be
sure: this is an x86 jail on an x86 system? I want to make sure it's
a jail issue and not a 32-bit emulation issue.

It's an x86 jail on an amd64 host.
