Thank you Sergey. Good call adding -c to list capabilities. There are some differences between your card and mine (I also added -e to list errors):

$ freebsd-version                                                                                                                                                                                                 12.0-RELEASE-p9

$ pciconf -lvce ix0
ix0 at pci0:17:0:0:        class=0x020000 card=0x17d3103c chip=0x10fb8086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
    class      = network

    cap 01[40] = powerspec 3  supports D0 D3  current D0
    cap 05[50] = MSI supports 1 message, 64 bit, vector masks enabled with 1 message
    cap 11[70] = MSI-X supports 64 messages
                 Table in map 0x1c[0x0], PBA in map 0x1c[0x2000]
    cap 10[a0] = PCI-Express 2 endpoint max data 256(512) FLR RO NS
                 link x8(x8) speed 5.0(5.0) ASPM disabled(L0s)
    cap 03[e0] = VPD

    ecap 0003[140] = Serial 1 48df37ffff62be38
    ecap 000e[150] = ARI 1
    ecap 0010[160] = SR-IOV 1 IOV disabled, Memory Space disabled, ARI enabled

  PCI-e errors = Correctable Error Detected
                 Unsupported Request Detected
     Corrected = Advisory Non-Fatal Error

I confirmed that it's not just a difference between hosts; when I boot the 11.3-RELEASE memstick image on this very same machine the NIC is properly configured with all 8 queues. So it's almost certainly a difference between ixgbe driver versions. I don't know if it matters, but this is an HPE branded Intel NIC in a DL380 Gen10.
