Hi,
I have been experiencing very poor network performance since Kernel
4.19 and I'm confident it's related to the r8169 driver.
I have no issue with kernel versions 4.18 and prior. I am experiencing
this issue in kernels 4.19 and 4.20 (currently running/testing with
4.20.4 & 4.19.18).
If someone could guide me in the right direction, I'm happy to help
troubleshoot this issue. Note that I have been keeping an eye on one
issue related to loading of the PHY driver, however, my symptoms
differ in that I still have a network connection. I have attempted to
reload the driver on a running system, but this does not improve the
situation.
Using the proprietary r8168 driver returns my device to proper working order.
