I think I'm asking you about the non RDMACM stuff in openmpi, ibcm,
xoob, etc. I can't tell at glance if any of them will be safe to run
on RDMAoE as-is..
Wait, I think I might have been mistaken. I'm looking through the
patches this morning and I don't see the "don't allow host-loopback if
it's IBoE" logic. The only places I see the check for real IB vs.
IBoE is when deciding to use IBCM or OOB connection schemes (which, as
Pasha said, are designed to be [real] IB only).
But, as you mentioned, there definitely are apps that don't use RDMACM
and use an "out of band" (i.e., OOB) mechanism for making IB QP's.
They therefore might have similar issues (need to check for real IB
vs. IBoE).
Sorry for the confusion... I'm going to chalk it up to the fact that
it was late at night when I sent that. :-)
