Title:
  TCP offloads disabled by default

Status in systemd:
  Unknown
Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Zesty:
  Fix Committed
Status in systemd package in Debian:
  Fix Released

Bug description:
  [Impact]
  Regression in systemd v232 resulted in IPv4 TCP segmentation offload ("tso" in ethtool) to be disabled by default, yet previously it was enabled.

  [Fix]
  Backport upstream patch to fix the regression

  [Testcase]
  Use ethtool to verify that tso is enabled on e.g. e1000e card with fixed package.

  [Regression Potential]
  Link features were incorrectly initialised, this fix changes the initialisation code back to the correct default values. This changes the defaults back to what they are in all other releases. Users on zesty release may have been accustomed to the wrong defaults and may need to adjust .link files to e.g. disable tso if that is the behavior they want.
