如何禁用 TX 校验和卸载

网卡上的校验和卸载可能会导致某些设置出现问题，包括 VMware 实例和 Cilium 中的设置。

如果遇到此类问题，您必须通过运行以下命令来禁用 TX 校验和卸载：

• 对于服务器计算机：

  cat <<EOF | sudo tee /etc/systemd/system/disable-checksum.service
  [Unit]
  Description=Disable TX Checksum Offload
  Before=rke2-server.service
  Wants=network-online.target
  After=network-online.target
  
  [Service]
  Type=oneshot
  ExecStart=/bin/bash -c "ethtool -K $(awk '$2 == 00000000 { print $1; exit }' /proc/net/route) tx-checksum-ip-generic off || ethtool -K cilium_host tx-checksum-ip-generic off || true"
  RemainAfterExit=true
  
  [Install]
  WantedBy=multi-user.target
  EOF
  sudo systemctl enable disable-checksum
