Yes, indeed. I have successfully changed both the primary interface
and the miimon value **while the interface is up** by directly writing
to the /sys/class/net/bondX/bonding/{Key} files. Changing the bonding
mode is not allowed while the interface is up (probably a good thing).

This is a great improvement over previous incarnations of Red Hat
bonding support. I have even successfully configured two bonds on the
same machine using different bonding modes for each. VERY useful!
