I see two solutions:
1) check the length in all drivers to ensure correctness.
2) when bonding changes it's type, flush mc addresses and start over.

Second option looks nicer to me, but I might be missing something, thouths?

If bonding is causing this problem, perhaps we should make bonding
go through a programmatic interface to do it's work so that the
check can be done generically and in a place that will get
caught during code changes and audits.
