PATCH 1/4 i40e: Replace one-element array with flex-array member in struct i40e_package_header
One-element and zero-length arrays are deprecated. So, replace one-element array in struct i40e_package_header with flexible-array member.
The + sizeof(u32) adjustments ensure that there are no differences in binary output.
