This used to be done in Ubuntu, as shown in bugs #991360 and #108862, and all my Windows hosts send it. However this was removed in Ubuntu due to a regression in IPv4 functionality. As IPv6 is more widely deployed these days, this regression in IPv6 should be fixed. This bug is current as of Ubuntu 16.04 LTS.
