[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server

why is the expected result 80%? we have historical data that
consistently demonstrates this the expectation or its some number we
have just decided on? so far this looks to me like a performance
enhancement request which we would not do for a stable kernel,
especially as there is a viable workaround. if this has been committed
upstream it will be in 25.04 and then filter through to 24.04.3

    r8169: enable SG/TSO on selected chip versions per default

    Due to problem reports in the past SG and TSO/TSO6 are disabled per
    default. It's not fully clear which chip versions are affected, so we
    may impact also users of unaffected chip versions, unless they know
    how to use ethtool for enabling SG/TSO/TSO6.
    Vendor drivers r8168/r8125 enable SG/TSO/TSO6 for selected chip
    versions per default, I'd interpret this as confirmation that these
    chip versions are unaffected. So let's do the same here.

[Where problems could occur]
When using iperf testing in the Ubuntu Certification Test Suite, The speed is only about 70%. (Expected result: Over 80%) This problem was initially discovered when the OS cert test suite was being executed.

[Other Info]
The OS scope in LENOVO is 24.04 server version, which are using Linux kernel 6.8, due to this reason, can this feature be backport to this version, thanks!
