Either way, it's a manual process to sync up -- except that grabbing 
from $somewhere/usr/include/linux/ethtool.h involves more steps and is 
potentially more error-prone.

And regardless of any of this, none of the sync-up stuff should have 
been in the same patch as your RXHASH additions.

Now that ethtool.git has the latest from net-next, it's a moot point anyway.
