[Bug 1021398] [NEW] ifup bridge devices does not work with inet6

[Jay R. Wren]

Public bug reported:

using a bridge device configured like this:

auto br0
iface br0 inet6 auto
iface br0 inet static
        address 10.8.10.192
        netmask 255.255.254.0
        gateway 10.8.10.1
        dns-nameservers 10.1.1.11 10.1.0.11
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0

auto eth0
iface eth0 inet manual


yields an error when bringing up with ifup

error: "net.ipv6.conf.br0.accept_ra" is an unknown key
Failed to bring up br0.


commenting the inet6 line solves the problem.
