Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:

Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:

Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:

Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:

Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:

Upon plugging in a USB adapter for NBase-T ethernet with an Realtek chip RTL8156 the kernel module cdc_ncm starts flooding /var/log/syslog with unneccessary status info.
The status lines either say that there's no ethernet link or show the interface as connected and state the link speed.
The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this:
