Doesn't this mean that ethtool -p will hold the RTNL lock forever?
Is this a good idea?

For example on the Red Hat machine I have here if you do:

ethtool -p eth2 100000 &
reboot

Various things the shutdown scripts try to do will fail because of the
held RTNL lock. in the end the script dies and the machine does not
reboot.
