Re: [PATCH net-next 06/10] {NET,IB}/mlx4: Add device managed flow steering firmware API

Just in case you guys _really_ and _truly_ are so unable to think
outside the box that you can't come up with something reasonable, I'll
get you started with two ideas:

1) A special "chipset" dummy netdev that a special class of ethtool
   commands can run on to set these things.

2) A "chipset" genetlink family with suitable operations and
   attributes.

In both cases appropriate mechanisms are added to make for keys that
are used for chipset matching, and device drivers simply register
a notifier handler that is called on two occaisions:

1) When settings are changed.

2) Upon initial handler registry, to acquire the initial settings.
