I've seen the STH post recommending the Chelsio T580, and the Intel XL710 as QSFP Ethernet (non-Infiniband) nics.
Are there any other options?
I know there is the connectx-2,3,4,5 series that have QSFP options, but I recall seeing quite a few posts about the connectx-2 and connectx-3 no longer working in freebsd11 due to dropped support.
If true, I suspect the trend will continue into freebsd12. If false, does anyone have experience with them running under 2.4.5?
