SubjectRe: netlink backwards compatibility in userspace tools
Hi Dave,

That seems wise. Thanks for the advice. A more sophisticated way of
approaching this would be for the kernel to also send a bitmap of
which attributes are "critical" and only warn (or even error) of
_those_ are not understood. But that seems needlessly complex, and so
I think I'll go with your suggestion, and simply warn once with a
shorter message.
