Hmm... Yes and no. The protocols (on a wire) are kinda external to the kernel
even if they are part of the kernel project as we usually define endianess
there and other things (like packing the data). The same applicable to the SW
protocols to commumicate with FW. But I haven't seen a clear documentation
on these cases and I see examples of all possible combinations of the types.
