Performing verification for Focal.

The affected user enabled -proposed and installed 5.4.0-66-generic to the system with a QLogic FastLinQ QL41000 Series 10/25/40/50GbE Controller.

They then set all interfaces down, and brought up the QLogic NIC only.

DNS lookup to an internal kubernetes domain with IPIP type DNS lookups work as intended, with tx checksumming enabled.

The kernel in -proposed fixes the issue, marking as verified.
