We would also need to consider DPDK code that’s dual-licensed. We have some code that’s dual BSD-GPLv2. IANAL, and I'm far from an expert on SW licensing, but I think Apache 2 is not compatible with GPLv2, so this might need to become Apache 2/GPLv3.

This might be a smaller task that you might think.

We get to 99%+ with 7-8 companies. Each company will probably want to do
a patent review on code they are contributing to see what they are
licensing (and this can be a lengthy task, but for some of the bigger
participants, this may already be an ongoing activity, or an acceptable
level of risk). You only need agreement from copyright holders, and it
is entirely possible that most participants work for companies that
retain the copyright to contributions.

Still, these can be a pain and a drag on momentum.

The Apache Software Foundation requires CLAs with copyright assignment
to the foundation for official Apache projects - this is to allow for
future license changes (an Apache v3 license), and also reflects some of
the difficulties of a 30 year old project (several of the original
copyright holders are no longer with the project, or have died, and the
succession rights for copyright materials can sometimes result in
unfortunate conflicts between the estates and open source projects).

My preference is to minimise change. I have no strong preference between
BSD + DCO and Apache v2. I would like to avoid a CLA.

Regards,
Dave.
