[ Upstream commit 22ccb684c1cae37411450e6e86a379cd3c29cb8f ]

Bonding only supports native XDP for specific modes, which can lead to confusion for users regarding why XDP loads successfully at times and fails at others. This patch enhances error handling by returning detailed error messages, providing users with clearer insights into the specific reasons for the failure when loading native XDP.
