Known bug: git.kernel.org

Bug

This topic is related to this proxmox issue: link

And this is what fixed my problem on DELL T7910 Workstation:

1) Go to /etc/network

auto lo
iface lo inet loopback

iface enp0s25 inet manual
    post-up /usr/sbin/ethtool -K $IFACE gso off tso off 2> /dev/null
    ethernet-wol g
auto vmbr0
iface vmbr0 inet static
    address 10.57.57.200/24
    gateway 10.57.57.1
    bridge-ports enp0s25
    bridge-stp off
    bridge-fd 0
    post-up /usr/sbin/ethtool -K $IFACE gso off tso off 2> /dev/null
iface enp9s0 inet manual


source /etc/network/interfaces.d/*

What these lines actually do ?

  • Disables Generic Segmentation Offload (GSO) and TCP Segmentation Offload (TSO) features for the network interface specified by $IFACE.
  • Redirects any error output (stderr) generated by the ethtool command to /dev/null, effectively suppressing error messages.
  • In summary, this command is used to disable certain offloading features for a specified network interface to potentially address networking issues or optimize network performance.
