Package: src:linux
Version: 5.10.40-1
Severity: normal
X-Debbugs-Cc: josh@joshtriplett.org

Some USB Ethernet devices using the cdc_ncm driver produce several of
these messages per second:

Jun 03 19:25:17 s kernel: cdc_ncm 3-2.2:2.0 enx(mac address): 1000 mbit/s downlink 1000 mbit/s uplink

This results in substantial log noise and disk usage.

Please consider backporting the upstream patch "net: usb: cdc_ncm: don't
spew notifications" (git commit
de658a195ee23ca6aaffe197d1d2ea040beea0a2), which fixes this problem.

Thank you,
Josh Triplett
