Comment # 8 on bug 1192874 from Takashi Iwai

Thanks!

Those correspond to the upstream commits

    e1000e: Fix packet loss on Tiger Lake and later

The latter is already included in the latest SLE15-SP3 kernel git branch but
the former isn't.  Will backport it.

Could you give the hwinfo output from your device?  Since SLE15-SP3 / Leap 15.3
kernel doesn't include the support for all those models (LM20-23 are missing),
we need to check whether it's really covered by that kernel.
