Network attributes error logs when using Talos OS

[aivanov-citc]

We use Talos as the operating system for kubernetes. NFD logs constantly show errors related to the network attributes of bonding_masters.

What happened:

E0819 06:20:51.415724       1 network.go:154] "failed to read net iface attribute" err="open /host-sys/class/net/bonding_masters/operstate: not a directory" attributeName="operstate"
E0819 06:20:51.415775       1 network.go:154] "failed to read net iface attribute" err="open /host-sys/class/net/bonding_masters/speed: not a directory" attributeName="speed"
I0819 06:20:51.816548       1 nfd-worker.go:664] "starting feature discovery..."
I0819 06:20:51.816977       1 nfd-worker.go:677] "feature discovery completed"

What you expected to happen:
Can you fix it so that this interface is ignored during scanning

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version): v1.30.3
• OS (e.g: cat /etc/os-release): Talos 1.7.6
• Kernel (e.g. uname -a): 6.6.43-talos

@aivanov-citc thanks for reporting the issue. Yes, I think we should ignore the bonding_masters "iface". The error itself is harmless even if annoying and distractive.

This does not appear to be fixed in 0.16.6, yet the PR/commit/patch is in that release.
