Hello, not sure if this the right place for this, if not, let me know where I should ask.

I purchased 2 of these adapters, XQ+85MP01D to use in an Chelsio Communications Inc. T62100-LP-CR in an eSXI 7.0 server, connected to a 40gbe switch, for whatever reason, when I use these adapters esxi only detects them a supporting 100 or 50 gbe, even tho the site says they're 40/100gbe. I looked at the support for the cards, and they list 40/50/100Gb. Am I better off returning these and buying overpriced Chelsio branded modules?
