Details

Description:
When bringing up a CONNECTION=vlan interface, an error message is displayed:

$ sudo netcfg -u Vlan999
:: Vlan999 up [BUSY]
error: "net.ipv6.conf.eth0.999.accept_ra" is an unknown key [DONE]

The sysctl key should be net.ipv6.conf.eth0/999.accept_ra" ("eth0/999" instead of "eth0.999"):
$ sysctl net.ipv6.conf.eth0/999.accept_ra
net.ipv6.conf.eth0/999.accept_ra = 1

$ ls /proc/sys/net/ipv6/conf/eth0.999/accept_ra
/proc/sys/net/ipv6/conf/eth0.999/accept_ra


Additional info:
* netcfg 2.6.8-1
* /etc/network.d/Vlan999:

<code text>
CONNECTION="vlan"
INTERFACE="eth0.999"
VLAN_PHYS_DEV="eth0"
VLAN_ID="999"
IP="static"
ADDR="1.99.0.120"
NETMASK="255.255.255.0"
</code>

Steps to reproduce:
$ netcfg -u Vlan999

I can confirm this bug. Note: ipv4 connetion works despite the error message.

* netcfg v2.6.8
# cat /etc/network.d/eth0.2
INTERFACE="eth0.2"
VLAN_PHYS_DEV="eth0"
VLAN_ID="2"
CONNECTION="vlan"
IP="dhcp"
DHCP_OPTIONS="--nogateway --nooption"

The following patch against /usr/lib/network/connections/ethernet from netcfg 2.6.8-1 changes the file in two ways:

1) it solves this issue by changing eth0.2 into eth0/2, which is the syntax accepted by sysctl

2) it doesn't disable routing advertisements for stateful DCHPv6, as routes aren't sent by the DHCP server, but rely on routing advertisements to be picked up by the client.

I verified Steve's patch on my system against netcfg 2.6.8-1

Thanks, Steve!

Here's a new patch updated for netcfg 2.7.1.
It fixes sysctl calls but doesn't change anything regarding DHCPv6 behavior.
