I saw the issue on both Ubuntu 16.04 and 18.04 with kernel versions 4.15.0-33-generic and 4.15.0-34-generic. The problem is not there for the latest released kernel version 4.15.0-36-generic.
I plan to continue testing for several more kernel releases for Ubuntu 16.04 and 18.04 for a while, to see if the issue reappears: https://github.com/jafingerhut/p4-guide/tree/master/linux-veth-bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782544 Title: tcpreplay and veth device; extra transmit bytes on 4.4.0-130-generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1782544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
