FYI - just redid this a few times. Looks like it's how long the system
was up, not copybreak wrt crash on resetting MTU.
That said, while the system seems OK after resetting the MTU, I do get a
WARNING from netdev watchdog - same warning regardless of copybreak.
Setting the mtu back to 1500 generates rx errors after which things
work. Going back to 9000 again does not generate new errors.
