Description js314592 2025-08-25 21:35:27 UTC

1. Please describe the problem:
USB Ethernet has often packet loss 
Realtek Semiconductor Corp. RTL8153 Gigabit Ethernet Adapter

2. What is the Version-Release number of the kernel:
6.16.3-200.fc42.x86_64 

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
6.15.10

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
ping facebook.com

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:


6. Are you running any modules that not shipped with directly Fedora's kernel?:


7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Reproducible: Always

Comment 1 pg_tips 2025-08-31 20:41:01 UTC

Could this in fact be the kernel bug described here (regression causing IPv4 broadcast packets to have their ethernet destination field mangled)? https://lore.kernel.org/regressions/20250822165231.4353-4-bacs@librecast.net/

If so, it also impacts wifi and "normal" (non-USB) ethernet users, for example as reported in https://discussion.fedoraproject.org/t/kernel-6-16-3-and-intel-ax200-wifi/163257

Comment 2 Dominik 'Rathann' Mierzejewski 2025-09-02 10:18:01 UTC

This is a regression in 6.16.

Comment 3 Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-09-03 12:35:42 UTC

The scope of the title should be expanded to encompass more than merely USB 802.3.
