2.6.29-rc* introduces a bug that causes a crash when a vlan is put into
another vlan, so called vlan trunking or QinQ.

I can reproduce it reliably with:

$ modprobe 8021q
$ vconfig add eth1 5
$ ifconfig eth1.5 up
$ vconfig add eth1.5 4

Stephen please fix this.

I'm maintaining vlan :) I haven't been able to look into this yet,
but I should be later today.
