I've been working on a Supermicro SYS-E300-9A (Intel Atom C3858,) putting together a fully virtualized router + whatever, and I'm getting around to being complete. The last step for me is routing my existing 10gbit setup through it, but I've hit a snag.
My NAS has a Mellanox ConnectX-2 card that previously ran into an identical card on my desktop using a direct attach cable. I am trying to route it into the Supermicro, but I have not yet been able to get it to link up.
Some notes:

Some notes:
- Initial interconnect was a Cisco direct attach cable. Worked fine between Mellanox adapters, but would not link up between the X553s in the Supermicro, let alone between Mellanox and Intel.
- New direct attach cable worked between like adapters, but not between Mellanox and Intel.
- Picked up some Finisar transceivers and one Intel transceiver (to be safe) and between like adapters, everything works with any permutation of transceivers. Between Mellanox and Intel, nothing works.
- Mellanox-delivered mlnx_en driver ignores ConnectX-2.
- Intel out-of-tree drivers have been tried, no change.
