We have some LGA1151 XEON based 19 inch rack server, also equipted with Has=
well
E3-12XX-v3 XEONs and FreeBSD, also CURRENT, does show AES-NI.
You're right, the vendor could have disabled AES-NI by intention - but they=
offered this
box especially with AES-NI capabilities.=20
See here:

i0-on-Intel-XEON-E5-1650-v3-on-Fujitsu-Celsius-M740-td6028895.html
I feel a bit pissed off right now due to Fujitsu, because we started testin=
g some
encrypting features and I'd like to use AES-NI and I run into this issue ag=
ain.
I need to know that FreeBSD is not the issue with this specific CPU type. I=
'm still
frustrated by that stupid comment "UNIX is not supoorted" I got that time t=
hen when I
reported 2015 the issue to Fujitsu.
