Contains some notes about using a Supermicro AOC-STGF-i2S - User's Guide
Initial configuration was:
- The DIP Switch at S1 was all off.
- The NC-SI Header was left unconnected as just fitting in a standard PC PCIe slot.
The User's Guide mentions the DIP Switch S1 provides the ''SMBUS address selection'' but not immediately clear if the SMBus is only active when the NC-SI Header is used.
There is a Nuvoton NCT6683D-T on the network adapter. Found the NCT6686D datasheet, but not sure how different from the NCT6683D-T.
Installed the network adapter, connected both ports to a 10G Ethernet switch with DAC cables, and booted Windows 10 Pro 22H2.
The links were up but Windows 10 was unable to find drivers.
lspci from pciutils-3.5.5-win64 idendified the network adapter as an Intel X710, with a Supermicro subsystem:

The Driver_Download.txt text file on the Supermicro download site says for Intel adapters to download https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html
Downloaded Release_28.1.1.zip. Ran Autorun.exe accepting defaults and the drivers were installed. ipconfig /all shows DHCP has allocated an IP address for both ports. The Description in the ipconfig output is Intel(R) Ethernet Controller X710 for 10GbE SFP+.
With a 4.18.0-477.13.1.el8_8.x86_64 Kernel the i40e Kernel module was loaded for the device.
Was able to use Network Manager to connect the devices, which were assigned an IP address using DHCP.
Looks like the i40e module has also loaded irdma but as expected no RDMA devices are available as the Intel-X710 is not documented as supporting RDMA:
$ lsmod|grep irdma
irdma 364544 0
ice 843776 1 irdma
ib_uverbs 163840 1 irdma
ib_core 397312 2 irdma,ib_uverbs
i40e 507904 1 irdma

------ ----------------
Whereas the Intel-X722 does support iWARP and uses the same module as the Intel-X710.
Booted into Windows 11 22H2.
Windows 11 found an Intel driver version 1.16.62.0, the link connected to a switch was up and an IP address had been allocated by DHCP. The Description in the ipconfig output is Intel(R) Ethernet Controller X710 for 10GbE SFP+.
Installed in a HP Z6 G4 running Windows 11 Pro Version 24H2 (OS Build 26100.3775).
No drivers were detected.
Under Windows Updated under Optional updates selected to install Intel - Net 6/14/2019 12:00:00 AM - 1.10.128.0.
That installed the drivers, and the following network interfaces appeared:
- Intel(R) Ethernet Controller X710 for 10GbE SFP+
- Intel(R) Ethernet Controller X710 for 10GbE SFP+ #2
One port had a SFP DAC cable connected to a 10G switch, and an IP address was allocated via DHCP.
