Hello Intel team,I have Intel NUC13ANKI5 machine, with I226-V network card, and gigabit Internet connection.
After (presumably) latest UEFI v0033 update for the NUC, my network is limited to ~250 Mbit/s download unless I disable PCIE ASPM option in UEFI settings.
ASUS support (which now handles support for NUC products) has confirmed the issue and provided me with Windows NetAdapterCx 2.1.4.3 driver, which has this issue fixed (I have not tested it on Windows).
Linux drivers are not fixed. I'm seeing the issue on Fedora 39, just tested network speed with PCIE ASPM enabled on 6.12.3-200.vanilla.fc39.x86_64 kernel - the issue is still here, 25 MB/s download max.
Let me know if you need debug output of igc driver, I can run any tests.56:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller I226-V [8086:125c] (rev 04)
