I think we should consider 4.17, which should hit RC1 around 4/15.   If
we kept our sparse kernel tree refreshed as the RCs progress, it should
be doable.  And it allows OFED to not lag so far behind upstream
releases.  My 2 cents...

Or at least 4.16.  I'm not sure why we would consider 4.15.x...

I thought we just supported the last 2 releases or something like that?
