Kip, good day.
Was just passing by, but found an interesting point?

I was under impression that OFED provides drivers for Mellanox. At
least I am using OFED 1.2 for Mellanox Arbel InfiniHost III, and I was
under impression that even ConnectX cards are supported by the 1.3.x as
well. Particularily, the ofa_kernel component of OFED build provides
core, HW and ULPs kernel modules.
I think that OFED sources can be taken and ported (at least partially,
for example, the driver parts) to provide kernel drivers for the cards.
Am I missing something?
