...similar comments about only using __packed where you really need it...
This pack is required as it is shared with hardware and need to be of 16 bytes for 32 and 64 bit architecture. Do not wanted to take risk of different compiler versions. So keeping it packed.

...similar comment about using readable typesafe inline functions instead of

Yes, I'll change to inline function.
