tl;dr - I'm trying to connect a ConnectX-4 MCX4131A-BCAT to a ConnectX-3 MCX354A at 40GbE. My Kaiam XQX2502's only seem to negotiate 1GbE. Is there a transceiver that will get me back to 40Gbps?
Previously, I had two ConnectX-3 MCX354A's connected (Windows to Linux) with Kaiam XQX2502's linked...

I purchased 1 ConnectX3 40GB dual port card for the Dell server (part number MCX354A-QCBT).

I picked up a nearly-new Epyc motherboard through the forums a few days ago, and for some reason it's not picking up my ConnectX-3 card at all (single port, 10GbE, I believe MCX311A-XCAT). I've tried multiple slots, and it's neither included in the IPMI inventory nor in lspci output, and there's...
