No, you can't do that either.  Basically you can't change the size or
layout of any of the ethtool structures.

Ok. Can you suggest me how I should add rx_copybreak to ethtool?

May be add another function, set/get_rxcopybreak(), to ethtool_ops?

Thanks

Should I drop the idea of ethtool and resubmit just the rx_copybreak changes?
(use module parameter to change rx_copybreak value).

Or should I try something like this
3de0b592394d17b 'ethtool: Support for configurable RSS hash key', Create new
ethtool cmd for changing driver rx_copybreak value.

Thanks
