xskfwd fails with error 0x80070002

[jamwaffles]

My end goal is to use the AF_XDP functionality in this project to send Ethernet II frames containing EtherCAT packets without bothering the rest of the network stack. To get started with this repo I thought I'd just try running an existing example. I followed the development.md guide and, after installing VS2022 and all the build dependencies, I ran:

• .\tools\build.ps1
• .\tools\prepare-machine.ps1 -ForSpinxskTest
• .\artifacts\bin\x64_Debug\test\xskfwd.exe 13

The last command fails with ERR: XskCreate failed: 80070002. I searched around and didn't find anything about that specific error code so, assuming it was permissions based, tried to run the binary in an admin powershell but that didn't change anything. I also did the whole set-executionpolicy unrestricted dance to no avail.

I appreciate ForSpinxskTest doesn't include the string xskfwd but I figured they'd need similar setup so went with it.

My NICs look like this (from netsh int ipv4 show interfaces):

Idx     Met         MTU          State                Name
---  ----------  ----------  ------------  ---------------------------
  1          75  4294967295  connected     Loopback Pseudo-Interface 1
 19          35        1500  connected     Wi-Fi
 17          65        1500  disconnected  Bluetooth Network Connection
  3          25        1500  disconnected  Local Area Connection* 1
  6          25        1500  disconnected  Local Area Connection* 2
 13          25        1500  connected     Ethernet 3
  5           5        1500  disconnected  Ethernet 4

Neither Ethernet 3 nor Ethernet 4 have anything connected to them, although the same error message is printed if I do plug a cable in. They're both Intel i226-V chipsets with Intel driver version 2.1.3.3. I'm on Windows 11 Pro 24H2.

Is there a common thing I need to do/change/configure to be able to run the examples (and subsequently my own programs with AF_XDP)? I'm a very new Windows developer so hopefully something obvious I've missed.
