I can imagine the case when app wants to enable jumbo MTU in
run-time, but enabling requires to know it in advance in order
to configure HW correctly (i.e. offload is needed).
I think it may be ignored. Driver should either reject MTU
set in started state or do restart automatically on request.
However, driver maintainers should keep it in mind reviewing
the patch.

I'm not sure that it is a step in right direction.
May be it is better to keep dev unused.
net/e1000 maintainers should decide.
