Hi Don

All this discussion is now a mute point. GregKH has spoken.

But i'm sure there are some on the side lines, eating popcorn, maybe
learning from the discussion.

Would you think it is O.K. to add a KAPI which works for 3 1/2" SCSI
disks, but not 2", because you only make machines with 3 1/2" bays?

This is an extreme, absurd example, but hopefully you get the
point. We don't design KAPIs with the intention to only work for a
subset of devices. It needs to work with as many devices as possible,
even if the first implementation below the KAPI is limited to just a
subset.

Anyway, i'm gratefull you have looked at the new ethtool netlink
KAPI. It will be better for your contributions. And i hope you can
make use of it in the future. But i think this discussion about optoe
in mainline is over.
