CURRENT: FreeBSD not reporting AES-NI on Intel(R) Xeon(R) CPU E5-1650 v3

[Chris H]

Apologies for top posting (I generally HATE that too),
and also, if someone already shared this link.
BUT; I performed a search at my favorite CPU spec site,
and it appears that your CPU *does* have AES-NI ( AESNI ):

http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20E5-1650%20v3.html

TL,DR:
    MMX instructions
    SSE / Streaming SIMD Extensions
    SSE2 / Streaming SIMD Extensions
    SSE3 / Streaming SIMD Extensions
    SSSE3 / Supplemental Streaming SIMD Extensions 3
    SSE4 / SSE4.1 + SSE4.2 / Streaming SIMD Extensions 4
    AES / Advanced Encryption Standard instructions
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    AVX / Advanced Vector Extensions
    AVX2 / Advanced Vector Extensions 2.0
    BMI / BMI1 + BMI2 / Bit Manipulation instructions
    F16C / 16-bit Floating-Point conversion instructions
    FMA3 / 3-operand Fused Multiply-Add instructions
    EM64T / Extended Memory 64 technology / Intel 64
    NX / XD / Execute disable bit
    HT / Hyper-Threading technology
    VT-x / Virtualization technology
    VT-d / Virtualization for directed I/O
    TBT 2.0 / Turbo Boost technology 2.0
    TXT / Trusted Execution technology

You also indicated that sysutils/dmidecode failed for you.
Could that mean that your lib(s) aren't in sync? Which
might contribute to this anomaly? Just a thought.

HTH
