and all the structures that include it. this should not change anything while avoiding packed vs alignment warnings from GCC 8, and potentially pessimised code generation due to the packed marker (there are no misaligned members, just that the per-device parts may end unaligned.) all consumers of these members are done from the properly aligned packet members directly, or, as a union with a 64 byte member, also properly aligned. codegen didn't appear to change, except for the definition of sizeof(struct driver_[rt]x_radiotap_header) in debug info, which is not directly used anywhere.
