Intel EHL: Two of the on-board ethernet ports don't work

This bug is awaiting verification that the linux-intel-5.13/5.13.0-1009.9 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Confirmed with Kent Lin, he has verified the proposed kernel on an Elkhart Lake board, the problem is fixed.

This bug was fixed in the package linux-intel-5.13 - 5.13.0-1009.9
