Way back when, in the olden days, I seem to remember that the first OSA 
address of a triplet used by Linux guests had to be an even address.

But then there are also vague memories of more recent information that as 
long as the first OSA vdev of a triplet seen by a guest is even, it does 
not matter if its rdev is odd.  Is that true, or have I been sneaking sips 
of Adam's cough medicine?

If the first vdev of the triplet being even is all that matters, do all 
the rdevs have to be in ascending sequential order? 

Or could we harvest all those lone, odd-numbered OSA rdevs?  E.g. "7000, 
7001, 7002" used, reclaim the abandoned 7003 rdev to be assigned as an 
even-numbered vdev, "7004, 7005, 7006" used, reclaim the abandoned 7007 
rdev to be assigned as an even-numbered vdev, etc.)?

And... where is this documented that I obviously overlooked?  Of course if 
a restriction were removed, where would one find it documented except in 
old manuals and folklore?  :-)
