I don't know if you have a solution in mind wrt the behaviour of the
offloaded flag if it is not to do as it does now and let the bridge age
out dynamic entries. That led me to conclude that this patch-set cannot
use the offloaded flag, but you seem to suggest otherwise.

If you have a suggestion, feel free.
