Hi Florian

I did a quick test of all the ethtool operations which the driver
supports, including setting coalescing. I did not exhaustively try all
possible coalescing settings, but the ones i did try did not provoke a
data abort.

Still, it would make sense to implement begin and end, but only for
net-next.
