Re: [PATCH v2] net: Allow ethtool to set interface in loopback mode.

Since this is a boolean it SHOULD go into ethtool_flags rather than
being a high level operation.

It could do, but I though ETHTOOL_{G,S}FLAGS were intended for
controlling offload features.

It just seems the number of hooks keeps growing which takes more space
and increases complexity.

Is there any complication/downside to using flags in the (un?)likely event of 
wanting different flavors of loopback in the card?
