Issue with Intel E810 NIC: Unexpected Behavior with PHY Sync Commands

[Aber1]

Hello,

I've been working with the Intel E810-XXVDA4T NIC and have come across an unexpected behavior that I'd like to discuss and seek assistance on.

Setup:

Linux 5.11.22-100.fc32.x86_64

NIC: Intel E810

driver: ice
version: 1.12.6
firmware-version: 4.20 0x8001778b 1.3346.0
expansion-rom-version:
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Issue:

When I execute the following commands:

echo 1 0 > /sys/class/net/enp1s0f1/device/phy/synce

I got:

and

echo 0 0 > /sys/class/net/enp1s0f0/device/phy/synce

I got:

I observe that the pin gets closed. This behavior is unexpected, especially since enp1s0f1 and enp1s0f0 are not on the same bus.

Expected Behavior: Given that the two commands are addressing different buses, I would expect that the actions on one bus would not affect the other.

Question:

Is there a known reason for this behavior?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!

Best regards, 

Aviad
