Do not use the programming language's bit + * field definition. + * + * 4. Define macros for encode/decode of u8, u16 fields within + * the u32 variables. Use these macros for set/get of these fields. + * Try to use this to optimize the structure without bloating it with + * u32 variables for every lower sized field. + * + * 5. Do not use PACK/UNPACK attributes for the structures as each member + * variable is already 4-byte aligned by virtue of being a u32 + * type. + * + * 6.
