Hello,
I have an PRO/10GbE in a Dell R720, running FreeBSD 12.1, connected to a Unifi US-16-X switch. At present it is using an SFP transceiver. I wanted to move to SFP+.
I am not sure which card this is. The iDRAC tells me:
* Integrated NIC 1 - Intel(R) 2P X520/2P I350 rNDC
* the service tag claims this R720 was configured with a Intel X520 DP 10Gb DA/SFP+
with part number C63DV. Looking that up, the images I found are consistent with
what I have in the box. The NIC has room for two transceivers and two ethernet cables.
When the SFP+ transceiver is inserted, this message appears:
kernel: ix0: Unsupported SFP+ module type was detected.
I don't know if this is:
* the wrong transceiver - I've tried two [1]
* the card firmware rejects anything not on a whitelist [2]
* the transceiver is in the wrong slot [3]
* only does DAC on 10G [4]
Ideas and suggestions please. Thank you.

[1] - The working 1G SFP is a Fiberstore SFP1G-SX-85. I have tried a Fiberstore SFP-10GSR-85
and a Avago AFBR-703SDZ

[3] - there are two slots for transceiver in this unit - I thought I read something
about one being different from the other, but I cannot locate that now.
I tried inserting a second SFP+ into the second slot, but nothing seemed to change.
I suspect it is just for lagg.
