Well, SD_FLAG_CMD_XXX is not the opcode which use incremental numbering
scheme, but instead use ORed number, that only 1,2,4,8 makes sense. So
above 0x0080 looks strange, maybe we can specify two lower bits for
gateway flag and two higher bits for inter-sheep flag? In this
assumption, we can set

#define SD_FLAG_CMD_RECOVERY 0x0100

Thanks,
