Send speed (means upload/TX) does not reach full Gigabit speed. Tested with iperf3 it hovers around 780Mbit/s max.
This is a known bug. See:
Disabling TCP segmentation offload via ethtool works as workaround.
As upstream does not seem to fix this, is there any chance we get a Kernel patch from gentoo (like Ubuntu did)?
Steps to Reproduce:
1.Use Intel I219-V NIC.
2.Test transmit speed via iperf3 or Samba or whatever.
Upload speed max 780Mbit/s
Upload speed should reach around 940Mbit/s.
