802.1ad on ixgbe vfs

[DLOBE]

Hi,

I am trying to configure 802.1ad on ixgbe vfs with a goal of moving resultant q-in-q interface into a container i.e. have the vf in default namespace and have all the vf's vlan interfaces being moved to different namespaces. Theoretically in this configuration, packets would be double-tagged coming into pf, be directed to correct vf (and outer tag stripped) and then delivered to linux with single-tag.

I tried this:

# echo 32 > /sys/class/net/eth1/device/sriov_numvfs

# ip link set dev eth1 up

# ip link set dev eth1 vf 1 vlan 2 proto 802.1ad

RTNETLINK answers: Protocol not supported

Is there a way I can do this ?

TIA,

Don.
