Add helper functions to support double tunneling GSO testing. Since certain
tunnel-specific parameters (e.g., gro-hint) are not yet supported by the
standard ip-link tool, this patch adds a new helper function utilizing
the ynl-cli to handle these extended netlink attributes.
As the YNL Python module cannot be invoked across different devices or
environments directly in its current form, the helper abstracts the
YNL CLI calls to ensure proper configuration of the tunneling device
features.

Add a new test case to verify GSO behavior for double-encapsulated Geneve
tunnels. This ensures that hardware drivers and the network stack correctly
handle nested tunnel headers during segmentation.
To maintain consistency and avoid complexity in hardware parser logic, the
test case ensures that the IP versions for both the inner and outer headers
remain the same.
