Hi,
I'm using an ASRock Rack EPC612D8A-TB motherboard with two Intel onboard NICs (I210 (Ethernet 2) and I217-LM (Ethernet)), running Win 8.1 Pro x64 with all Windows Updates installed and the latest Intel Ethernet driver package (20.2.3001.0). My problem is with the I217-LM, according to the Intel spec sheet it does support RSS (cp. figure on page 2).
In the I217-LM's advanced driver settings there is an option to enable and disable RSS. However Windows itself always says that the I217-LM is not RSS-capable.
The same option in the I210 driver options has the expected effect: With the PowerShell command get-SmbClientNetworkInterface you can see the RSS capability changing from True to False and vice versa.
Can anyone tell why the I217-LM is not getting the RSS feature?
Further system details:
CPU: Xeon E5-1620-V3
RAM: 2 x 16 GiB Crucial DDR4-2133 ECC
The motherboard does not have a later BIOS/UEFI release than the one installed.
Thank you very much for your help!
