One loosely related question: how sure can we be that we are never going
to need more than 32 bits for FEC encodings? Is it something completely
hypothetical or is it something that could happen in the future?

Hi Michal

Hopefully we have moved to a netlink socket by that time :-)

I recently found that EEE still uses a u32 for advertise link modes.
We should fix that in the netlink API.
