[openstack-dev] [infra][neutron] - best way to load 8021q kernel module into cirros

The problem with the other projects image builds is that they are
based for bigger systems, while cirros is an embedded-device-like
image which boots in a couple of seconds.

Couldn't we contribute to cirros to have such module load by default [1]?

Or may be it's time for Openstack to build their own "cirros-like"
image with all the capabilities we may be missing for general tempest
testing? (ipv6, vlan, etc..? )
