From: Shigeru Yoshida <syoshida@xxxxxxxxxx> [ Upstream commit c7f2188d68c114095660a950b7e880a1e5a71c8f ] The function bpf_test_init() now returns an error if user_size (.data_size_in) is less than ETH_HLEN, causing the tests to fail. Adjust the data size to ensure it meets the requirement of ETH_HLEN.
