Bonding driver makes bad use of ethtool

ethtool is being abused by the bonding driver.  ifenslave is passing
in which ABI version it wants to use via the ETHTOOL_GDRVINFO call.
This cannot continue in the ethtool_ops scheme, and it's my opinion this
shouldn't've been done in the first place.

I suggest a new ioctl to set your ABI version and delete this bad use
of ETHTOOL_GDRVINFO.
