As ethtool over netlink has some limitations of the size,
I believe you can configure ethtool with "--disable-netlink" and set those message levels fine

Yup, IIUC it works for Paul on a 5.17 system, that system likely has
old ethtool user space tool which uses ioctls instead of netlink.

What makes the netlink path somewhat non-trivial is that there is 
an expectation that the communication can be based on names (strings)
as well as bit positions. I think we'd need a complete parallel
attribute to carry vendor specific bits :S

Yes, that would be a way to go. However, in such case I would prefer
separating these driver/device specific message flags completely rather
then letting drivers grab currently unused flags (as is the case here,
IIUC) as those are likely to collide with future global ones.
