    e1000e: Disable TSO on i219-LM card to increase speed

    While using i219-LM card currently it was only possible to achieve
    about 60% of maximum speed due to regression introduced in Linux 5.8.
    This was caused by TSO not being disabled by default despite commit
    f29801030ac6 ("e1000e: Disable TSO for buffer overrun workaround").
    Fix that by disabling TSO during driver probe.
